Abstract
Matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) are collectively known as gelatinases whereas MMP-2 is gelatinase-A and MMP-9 is termed as gelatinase-B. Gelatinases and other matrix metalloproteinases (MMPs) have long been associated with solid tumor invasion, metastasis and angiogenesis. However, there is paucity of data available regarding the role of gelatinases in hematological malignancies. Recent studies have shown that gelatinases activities or functions are correlated with hematological malignancies. Strategies for designing more specific gelatinase inhibitors like catalytic (CAT) domain inhibitors and hemopexin (PEX) domain inhibitors as well as signaling pathway based or gelatinase expression inhibitors had been reported against hematologic malignant cells. Several substrate based non-selective to non-substrate based relatively selective synthetic matrix metalloproteinase inhibitors (MMPIs) had been developed. Few MMPIs had reached in clinical trials during the period of 1990s-2000s. Unfortunately the anti-tumor and anti-metastatic efficacies of these MMPIs were not justified with patients having several advanced stage solid tumor cancers in any substantial number of clinical trials. Till date not a single MMPI passed phase III clinical trials designed for advanced metastatic cancers due to adverse events as well as lack of ability to show uniformity in disease prolongation. With the best of our knowledge no clinical trial study has been reported with small molecule synthetic inhibitors against hematological malignancies. This review looks at the outcome of clinical trials of MMPIs for advanced stage solid tumors. This can therefore, act as a learning experience for future development of successful gelatinase inhibitors for the management of hematological malignancies.

Abstract
Matrix metalloproteinase (MMP) is a class of metalloenzyme that cleaves peptide bonds in extracellular matrices. Their functions are important in both health and disease of animals. Here using quantum mechanics simulations of the MMP8 protein, the coordination chemistry of different metal cofactors is examined. Structural comparisons reveal that Jhan-Teller effects induced by Cu(II) coordination distorts the wild-type MMP8 active site corresponding to a significant reduction in activity observed in previous experiments. In addition, further analysis suggests that a histidine to glutamine mutation at residue number 197 can potentially allow the MMP8 protein to utilize Cu(II) in reactions. Simulations also demonstrates the requirement of a conformational change in the ligand before enzymatic cleavage. The insights provided here will assist future protein engineering efforts utilizing the MMP8 protein.

Abstract
Matrix Metalloproteinase-1 (MMP-1) has been often upregulated in advanced breast cancers, known to participate in ECM degradation, migration, invasion, thus leading to metastasis. Due to these effects, the condition is often reported to inversely correlate with survival in advanced breast cancers. In the present study, in-silico method was adopted based on selective non zinc binding inhibitors of MMP-1. ADME properties were predicted for PASS filtered compounds and docking calculations were performed using Glide XP and IFD protocols of Schrodinger program. We identified six ligands as potent inhibitors and validated by observing structures and the interactions of MMP-1. The identified hits were validated using molecular dynamics simulation studies. Electronic structure analysis was performed for two top hit compounds myricetin and quercetin using density function theory (DFT) at B3LYP/6-31**G level to understand their molecular reactivity. Finally, one compound myricetin has emerged as the structurally stable compound with -7.801 kcal/mol and reasonable pose inside the binding site. Molecular dynamics results indicated that myricetin forms a stable interaction with the key amino acid residues such as Glu209, Glu219, Tyr240 and Pro238. In addition, it did not form any binding with the catalytic zinc at its active site. The interaction pattern of myricetin at its substrate binding site exhibited to be potent MMP-1 inhibitor. DFT study also showed that it has more potent inhibitory effect and solubility. These factors altogether show that myricetin could be considered as the best among the compounds evaluated in inhibiting MMP-1 thereby preventing metastasis of breast cancer.

Abstract
Matrix metalloproteinases hydrolyze proteins and glycoproteins forming the extracellular matrix, cytokines and growth factors released in the extracellular space, and membrane-bound receptors on the outer cell membrane. The pathological relevance of MMPs has prompted the structural and functional characterization of these enzymes and the development of synthetic inhibitors as possible drug candidates. Recent studies have provided a better understanding of the substrate preference of the different members of the family, and structural data on the mechanism by which these enzymes hydrolyze the substrates. Here, we report the recent advancements in the understanding of the mechanism of collagenolysis and elastolysis, and we discuss the perspectives of new therapeutic strategies for targeting MMPs.

Abstract
Matrix metalloproteinases (MMPs) are zinc-dependent proteolytic enzymes that degrade various proteins in the extracellular matrix (ECM). MMPs may also regulate the activity of membrane receptors and postreceptor signaling mechanisms and thereby affect cell function. The MMP family includes collagenases, gelatinases, stromelysins, matrilysins, membrane-type MMPs, and other MMPs. Inactive proMMPs are cleaved by other MMPs or proteases into active MMPs, which interact with various protein substrates in ECM and cell surface. MMPs regulate important biological processes such as vascular remodeling and angiogenesis and may be involved in the pathogenesis of cardiovascular disorders such as hypertension, atherosclerosis, and aneurysm. The role of MMPs is often assessed by measuring their mRNA expression, protein levels, and proteolytic activity using gel zymography. MMP inhibitors are also used to assess the role of MMPs in different biological processes and pathological conditions. MMP activity is regulated by endogenous tissue inhibitors of metalloproteinases (TIMPs), and the MMP/TIMP balance could determine the net MMP activity, ECM turnover, and tissue remodeling. Also, several synthetic MMP inhibitors have been developed. Synthetic MMP inhibitors include a large number of zinc-binding globulins (ZBGs), in addition to non-ZBGs and mechanism-based inhibitors. MMP inhibitors have been proposed as potential tools in the management of osteoarthritis, cancer, and cardiovascular disorders. However, most MMP inhibitors have broad-spectrum actions on multiple MMPs and could cause undesirable musculoskeletal side effects. Currently, doxycycline is the only MMP inhibitor approved by the Food and Drug Administration. New generation biological and synthetic MMP inhibitors may show greater MMP specificity and fewer side effects and could be useful in targeting specific MMPs, reducing unrestrained tissue remodeling, and the management of MMP-related pathological disorders.

Abstract
Human matrix metalloproteinase (MMP)-1 or collagenase-1 plays a significant role in embryonic development, tissue remodeling, and is also involved in several diseases like arthritis, metastasis, etc. Molecular dynamics simulation studies on hMMP-1 X-ray structures (PDB Id. 1CGE, 1CGF, 1CGL, 1HFC, and 2TCL) suggest that the three conserved water molecules (WH/1, WI, WS) are coordinated with catalytic zinc (ZnC), and one water molecule (W) is associated at structural zinc ion (ZnS). Transition of the coordination geometry around ZnC from tetrahedral to octahedral and tetrahedral to trigonal bipyramidal at ZnS are also observed during the dynamics. Recognition of two zinc ions through water mediated bridges (ZnC - WH (W1)…W2….H183 - ZnS) and stabilization of secondary coordination zone around the metal ions indicates the possibility of ZnC…ZnS coupled catalytic mechanism in hMMP-I. This study not only reveals a functionally important role of conserved water molecules in hMMP-I but also highlights the involvement of other non catalytic residues, such as S172 and D170 in the catalytic mechanism. The results obtained in this study could be relevant for importance of conserved water mediated recognition site of the sequence residue id. 202(RWTNNFREY)210, interaction of W(tryptophan)203 to zinc bound histidine, their influence on the water molecules that are involved in bridging between ZnC and ZnS, and structure-based design of specific hMMP inhibitors.

Abstract
Snake venom metalloproteinases (SVMPs) play key biological roles in prey immobilization and digestion. The majority of these activities depend on the hydrolysis of relevant protein substrates in the tissues. Hereby, we describe several isoforms and a cDNA clone sequence, corresponding to PII SVMP homologues from the venom of the Central American pit viper Bothriechis lateralis, which have modifications in the residues of the canonical sequence of the zinc-binding motif HEXXHXXGXXH. As a consequence, the proteolytic activity of the isolated proteins was undetectable when tested on azocasein and gelatin. These PII isoforms comprise metalloproteinase and disintegrin domains in the mature protein, thus belonging to the subclass PIIb of SVMPs. PII SVMP homologues were devoid of hemorrhagic and in vitro coagulant activities, effects attributed to the enzymatic activity of SVMPs, but induced a mild edema. One of the isoforms presents the characteristic RGD sequence in the disintegrin domain and inhibits ADP- and collagen-induced platelet aggregation. Catalytically-inactive SVMP homologues may have been hitherto missed in the characterization of snake venoms. The presence of such enzymatically-inactive homologues in snake venoms and their possible toxic and adaptive roles deserve further investigation.

Abstract
Matrix metalloproteinase-1 (MMP-1) plays crucial roles in disease-related physiologies and pathological processes in the human body. We report here solution studies of MMP-1, including characterization of a series of mutants designed to bind metal in either the catalytic site or the structural site (but not both). Circular dichroism and fluorescence spectroscopy of the mutants demonstrate the importance of the structural Zn(II) in maintaining both secondary and tertiary structure, while UV-visible, nuclear magnetic resonance, electron paramagnetic resonance, and extended X-ray absorption fine structure show its presence influences the catalytic metal ion's coordination number. The mutants allow us to demonstrate convincingly the preparation of a mixed-metal analogue, Co(C)Zn(S)-MMP-1, with Zn(II) in the structural site and Co(II) in the catalytic site. Stopped-flow fluorescence of the native form, Zn(C)Zn(S)-MMP-1, and the mixed-metal Co(C)Zn(S)-MMP-1 analogue shows that the internal fluorescence of a nearby Trp residue is modulated with catalysis and can be used to monitor reactivity under a number of conditions, opening the door to substrate profiling.

Abstract
Many experimental studies have found that flavonoids can inhibit the activities of matrix metalloproteinases (MMPs), but the relevant mechanisms are still unclear. In this paper, the interaction mechanisms of MMP-9 with its five flavonoid inhibitors are investigated using a combination of molecular docking, hybrid quantum mechanical and molecular mechanical (QM/MM) calculations, and molecular dynamics simulations. The molecular dynamics simulation results show a good linear correlation between the calculated binding free energies of QM/MM−Poisson–Boltzmann surface area (PBSA) and the experimental −log(EC50) regarding the studied five flavonoids on MMP-9 inhibition in explicit solvent. It is found that compared with the MM−PBSA method, the QM/MM−PBSA method can obviously improve the accuracy for the calculated binding free energies. The predicted binding modes of the five flavonoid−MMP-9 complexes reveal that the different hydrogen bond networks can form besides producing the Zn−O coordination bonds, which can reasonably explain previous experimental results. The agreement between our calculated results and the previous experimental facts indicates that the force field parameters used here are effective and reliable for investigating the systems of flavonoid−MMP-9 interactions, and thus, these simulations and analyses could be reproduced for the other related systems involving protein−ligand interactions. This paper may be helpful for designing the new MMP-9 inhibitors having higher biological activities by carrying out the structural modifications of flavonoid molecules.

Abstract
We modeled the first steps of hydrolysis reactions of a natural oligopeptide substrate of matrix metalloproteinase MMP-2 as well as of a substrate analogue. In the latter, the scissile amide group is substituted by a ketomethylene group which can be transformed to the ketal group upon binding of this compound to the enzyme active site. According to our quantum mechanical-molecular mechanical (QM/MM) calculations, the reaction of the ketone-ketal transformation proceeds with a low energy barrier (3.4 kcal/mol) and a high equilibrium constant (10(4)). The reaction product with the ketal group formed directly at the active site of the enzyme works as an inhibitor that chelates the zinc ion. On the other hand, the oligopeptide mimetic retains molecular groups responsible for binding of this compound to the enzyme active site. This example illustrates a strategy to design MMP inhibitors in situ by using data on binding specificity of substrates to a particular type of MMP and details of the reaction mechanism.

Abstract
Many experimental studies have previously found that flavonoids including luteolin can inhibit the activities of matrix metalloproteinases (MMPs), but the related theoretical studies are rather lacking. In this paper, based on our recently obtained interaction mechanisms between luteolin and the catalytic zinc ion in MMPs (see J. Phys. Org. Chem. 2012, 25, 1306), we perform PM6 quantum chemistry calculations together with modeling of ligand−water exchange reactions to investigate the relevant structural modifications for the inhibition of MMP activities by luteolin. The calculations indicate that among the possible modified positions of A, B, and C rings of the luteolin molecule, 5, 7, 2′, 3′, and 4′ should be the five suitable modified positions, and the several usual substituent groups that have stronger electron-donating abilities should be the suitable substituent groups. We further find that with the increasing number of these substituent groups, the biological activities for the modified luteolin molecules on MMP inhibition can be obviously improved. Our calculated results are in agreement with previous relevant experimental results. This paper gives a new approach for designing the new MMP inhibitors having higher biological activities by carrying out the structural modifications of the luteolin molecule.

Abstract
Quantum chemistry calculations together with modeling of ligand–water exchange reactions are used to investigate, for the first time, the interaction mechanisms between emodin of anthraquinones and the catalytic zinc ion in matrix metalloproteinases (MMPs), and the coordinating mode between them is determined. The calculations indicate that the electron transfer from the emodin molecule to the catalytic zinc ion in MMPs occurs when the catalytic zinc ion coordinates with the O atoms of substituent groups at various positions of emodin molecule, and the more the number of the electron transfer from the coordinating O atom of substituent group of emodin molecule to the catalytic zinc ion, the stronger the coordinating ability between them. It is found that comparing with the O atoms of hydroxy groups at 1-position, 8-position and 3-position and the O atom of carbonyl group at 9-position of emodin molecule, the coordinating ability for the O atom of carbonyl group at 10-position of emodin molecule with the catalytic zinc ion in MMPs is the strongest. Therefore, when emodin inhibits MMPs activity, the catalytic zinc ion in MMPs should coordinate with the carbonyl group at 10-position of emodin molecule, rather than the hydroxy groups and carbonyl group at its other positions. Our calculated results are in agreement with previous relevant experimental results. This paper may be helpful for designing the new MMPs inhibitors having higher biological activities by carrying out the structural modifications of emodin molecule.

Abstract
BaP1 is a snake venom metalloproteinase from the venom of Bothrops asper, showing high structural homology with the catalytic domain of human adamalysins and matrix metalloproteinases. It induces the release of cytokines, like interleukin-1 and tumor necrosis factor alpha. Recently, the high-resolution crystal structure of BaP1 with a bound inhibitor became available, representing an interesting model concerning inhibitor design for medicinally important metalloproteinases such as tumor necrosis factor alpha-converting enzyme and MMP13. We here use computational modeling to gain a better understanding about the binding properties of various ligands to BaP1, with a focus on computing ligand binding free energies. The obtained results should be of general significance for future research on medicinally important metalloproteinases. We have investigated the binding of the original inhibitor in detail and calculated its binding strength using MMP/GBSA free energy calculations. Additionally, the binding strengths of alternative ligands have been computed, and two of them are predicted and experimentally verified to strongly inhibit the enzyme. A suggestion for chemical modifications of BaP1 inhibitors could be made to guide future synthesis efforts. Furthermore, a contribution to the proteolytic reaction mechanism of metzincins is given. The pK value of the catalytically active glutamic acid residue 143 has been found to be significantly raised when compared with a free glutamate side chain. Calculations on other matrix metalloproteinases confirmed that this is not confined to BaP1, but seems to be a common feature of metzincins.

Abstract
Matrix metalloproteinases (MMPs) are proteolytic enzymes that degrade various components of the extracellular matrix (ECM). MMPs could also regulate the activity of several non-ECM bioactive substrates and consequently affect different cellular functions. Members of the MMPs family include collagenases, gelatinases, stromelysins, matrilysins, membrane-type MMPs, and others. Pro-MMPs are cleaved into active MMPs, which in turn act on various substrates in the ECM and on the cell surface. MMPs play an important role in the regulation of numerous physiological processes including vascular remodeling and angiogenesis. MMPs may also be involved in vascular diseases such as hypertension, atherosclerosis, aortic aneurysm, and varicose veins. MMPs also play a role in the hemodynamic and vascular changes associated with pregnancy and preeclampsia. The role of MMPs is commonly assessed by measuring their gene expression, protein amount, and proteolytic activity using gel zymography. Because there are no specific activators of MMPs, MMP inhibitors are often used to investigate the role of MMPs in different physiologic processes and in the pathogenesis of specific diseases. MMP inhibitors include endogenous tissue inhibitors (TIMPs) and pharmacological inhibitors such as zinc chelators, doxycycline, and marimastat. MMP inhibitors have been evaluated as diagnostic and therapeutic tools in cancer, autoimmune disease, and cardiovascular disease. Although several MMP inhibitors have been synthesized and tested both experimentally and clinically, only one MMP inhibitor, i.e., doxycycline, is currently approved by the Food and Drug Administration. This is mainly due to the undesirable side effects of MMP inhibitors especially on the musculoskeletal system. While most experimental and clinical trials of MMP inhibitors have not demonstrated significant benefits, some trials still showed promising results. With the advent of new genetic and pharmacological tools, disease-specific MMP inhibitors with fewer undesirable effects are being developed and could be useful in the management of vascular disease.

Abstract
The stromelysin-1 catalytic domain(83-247) (SCD) is stable for at least 16 h at pHs 6.0-8.4. At pHs 5.0 and 9.0 there is exponential irreversible denaturation with half lives of 38 and 68 min respectively. At pHs 4.5 and 10.0 irreversible denaturation is biphasic. At 25°C, C-terminal truncation of stromelysin-1 decreases the stability of the stromelysin-1 catalytic domain at pH values >8.4 and <6.0. We describe the conversion of the carboxylate group of (βR)-β-[[[(1S)-1-[[[(1S)-2-Methoxy-1-phenylethyl]amino]carbonyl]-2,2-dimethylpropyl]amino]carbonyl]-2-methyl-[1,1'-biphenyl]-4-hexanoic acid (UK-370106-COOH) a potent inhibitor of the metalloprotease stromelysin-1 to a glyoxal group (UK-370106-CO(13)CHO). At pH 5.5-6.5 the glyoxal inhibitor is a potent inhibitor of stromelysin-1 (K(i)=~1μM). The aldehyde carbon of the glyoxal inhibitor was enriched with carbon-13 and using carbon-13 NMR we show that the glyoxal aldehyde carbon is fully hydrated when it is in aqueous solutions (90.4ppm) and also when it is bound to SCD (~92.0ppm). We conclude that the hemiacetal hydroxyl groups of the glyoxal inhibitor are not ionised when the glyoxal inhibitor is bound to SCD. The free enzyme pK(a) values associated with inhibitor binding were 5.9 and 6.2. The formation and breakdown of the signal at ~92ppm due to the bound UK-370106-CO(13)CHO inhibitor depends on pK(a) values of 5.8 and 7.8 respectively. No strong hydrogen bonds are present in free SCD or in SCD-inhibitor complexes. We conclude that the inhibitor glyoxal group is not directly coordinated to the catalytic zinc atom of SCD.

Abstract
This short review highlights some recent advances in matrix metalloproteinase inhibitor (MMPi) design and development. Three distinct approaches to improved MMP inhibition are discussed: (1) the identification and investigation of novel zinc-binding groups (ZBGs), (2) the study of non-zinc-binding MMPi, and (3) mechanism-based MMPi that form covalent adducts with the protein. Each of these strategies is discussed and their respective advantages and remaining challenges are highlighted. The studies discussed here bode well for the development of ever more selective, potent, and well-tolerated MMPi for treating several important disease pathologies.

Abstract
Matrix metalloproteinases (MMPs) are zinc-dependent protein and peptide hydrolases. They have been almost exclusively studied in vertebrates and 23 paralogs are present in humans. They are widely involved in metabolism regulation through both extensive protein degradation and selective peptide-bond hydrolysis. If MMPs are not subjected to exquisite spatial and temporal control, they become destructive, which can lead to pathologies such as arthritis, inflammation, and cancer. The main therapeutic strategy to combat the dysregulation of MMPs is the design of drugs to target their catalytic domains, for which purpose detailed structural knowledge is essential. The catalytic domains of 13 MMPs have been structurally analyzed so far and they belong to the "metzincin" clan of metalloendopeptidases. These compact, spherical, approximately 165-residue molecules are divided by a shallow substrate-binding crevice into an upper and a lower sub-domain. The molecules have an extended zinc-binding motif, HEXXHXXGXXH, which contains three zinc-binding histidines and a glutamate that acts as a general base/acid during catalysis. In addition, a conserved methionine lying within a "Met-turn" provides a hydrophobic base for the zinc-binding site. Further earmarks of MMPs are three alpha-helices and a five-stranded beta-sheet, as well as at least two calcium sites and a second zinc site with structural functions. Most MMPs are secreted as inactive zymogens with an N-terminal approximately 80-residue pro-domain, which folds into a three-helix globular domain and inhibits the catalytic zinc through a cysteine imbedded in a conserved motif, PRCGXPD. Removal of the pro-domain enables access of a catalytic solvent molecule and substrate molecules to the active-site cleft, which harbors a hydrophobic S(1')-pocket as main determinant of specificity. Together with the catalytic zinc ion, this pocket has been targeted since the onset of drug development against MMPs. However, the inability of first- and second-generation inhibitors to distinguish between different MMPs led to failures in clinical trials. More recent approaches have produced highly specific inhibitors to tackle selected MMPs, thus anticipating the development of more successful drugs in the near future. Further strategies should include the detailed structural characterization of the remaining ten MMPs to assist in achieving higher drug selectivity. In this review, we discuss the general architecture of MMP catalytic domains and its implication in function, zymogenic activation, and drug design.

Abstract
The structures of complexes between amides and metal ions were examined by FAB mass spectrometry and collision-induced dissociation (CID). Zn2+ was coordinated by the amide carbonyl oxygen atom of N-tetradecylacetamide (1). In contrast, Ca2+ and Mg2+ were coordinated by the amide group of 1 in both the keto and enol forms. The catalytic role of Zn2+ at the active site of the hydrolases might partly be explained by the effective attack of Zn2+ on carbonyl oxygen atom of the scissile amide group.

Abstract
Macrophage metalloelastase or matrix metalloproteinase-12 (MMP-12) appears to exacerbate atherosclerosis, emphysema, aortic aneurysm, rheumatoid arthritis, and inflammatory bowel disease. An inactivating E219A mutation, validated by crystallography and NMR spectra, prevents autolysis of MMP-12 and allows us to determine its NMR structure without an inhibitor. The structural ensemble of the catalytic domain without an inhibitor is based on 2813 nuclear Overhauser effects (NOEs) and has an average RMSD to the mean structure of 0.25 A for the backbone and 0.61 A for all heavy atoms for residues Trp109-Gly263. Compared to crystal structures of MMP-12, helix B (hB) at the active site is unexpectedly more deeply recessed under the beta-sheet. This opens a pocket between hB and beta-strand IV in the active-site cleft. Both hB and an internal cavity are shifted toward beta-strand I, beta-strand III, and helix A on the back side of the protease. About 25 internal NOE contacts distinguish the inhibitor-free solution structure and indicate hB's greater depth and proximity to the sheet and helix A. Line broadening and multiplicity of amide proton NMR peaks from hB are consistent with hB undergoing a slow conformational exchange among subtly different environments. Inhibitor-binding-induced perturbations of the NMR spectra of MMP-1 and MMP-3 map to similar locations across MMP-12 and encompass the internal conformational adjustments. Evolutionary trace analysis suggests a functionally important network of residues that encompasses most of the locations adjusting in conformation, including 18 residues with NOE contacts unique to inhibitor-free MMP-12. The conformational change, sequence analysis, and inhibitor perturbations of NMR spectra agree on the network they identify between structural scaffold and the active site of MMPs.

Abstract
Leucurolysin-B (leuc-B) is an hemorrhagic metalloproteinase found in the venom of Bothrops leucurus (white-tailed-jararaca) snake. By means of liquid chromatography consisting of gel filtration on Sephracryl S-200, S-300 and ion-exchange on DEAE Sepharose, leuc-B was purified to homogeneity. The proteinase has an apparent molecular mass of 55kDa as revealed by the reduced SDS-PAGE, and represents approximately 1.2% of the total protein in B. leucurus venom. The partial amino acid sequence of leuc-B was determined by automated Edman sequencing of peptides derived from digests of the S-reduced and alkylated protein with trypsin. Leuc-B exhibits the characteristic motif of metalloproteinases, HEXXHXXGXXH and a methionine-containing turn of similar conformation ("Met-turn"), which forms a hydrophobic basis for the zinc ions and the three histidine residues involved as ligands. Leuc-B has been characterized as a P-III metalloproteinase and possesses a multidomain structure including a metalloproteinase, a disintegrin-like (ECD sequence instead of the typical RGD motif) and a cysteine-rich C-terminal domain. Leuc-B contains three potential sites of N-glycosylation. The enzyme only cleaves the Ala14-Leu15 peptide bond of the oxidized insulin B-chain and preferentially hydrolyzes the Aalpha-chain of fibrinogen and the alpha-chain of fibrin. Its proteolytic activity was completely inhibited by metal chelating agents but not by other typical proteinase inhibitors. In addition, its enzymatic activity was stimulated by the divalent cations Ca2+ and Mg2+ but inhibited by Zn2+ and Cu2+. The catalytic activity of leuc-B on extracellular matrix proteins could readily lead to loss of capillary integrity resulting in hemorrhage occurring at those sites (MHD=30ng in rabbit), with alterations in platelet function. In summary, here we report the isolation and the structure-function relationship of a P-III snake venom metalloproteinase.

Abstract
We structurally characterized the adducts of the catalytic domain of matrix metalloproteinase-3 (MMP3) with three different nonpeptidic inhibitors by solving the solution structure of one adduct [MMP3-N-isobutyl-N-(4-methoxyphenylsulfonyl)glycyl hydroxamic acid] and then by calculating structural models of the other two adducts using a reduced set of experimental NMR data, following a recently proposed procedure (Bertini et al. in J. Med. Chem. 48:7544-7559, 2005). The inhibitors were selected with the criteria of maintaining in all of them the same zinc-coordinating moiety and of selectively changing the substituents and/or the functional groups. The backbone dynamics on various time scales have been characterized as well. The comparison among these structures and with others previously reported allowed us to elucidate fine details of inhibitor-receptor interactions and to develop some criteria, which could guide in optimizing the design of selective inhibitors.

Abstract
Matrix metalloproteinases (MMPs) are a large family of calcium-dependent zinc-containing endopeptidases, which are responsible for the tissue remodeling and degradation of the extracellular matrix (ECM), including collagens, elastins, gelatin, matrix glycoproteins, and proteoglycan. They are regulated by hormones, growth factors, and cytokines, and are involved in ovarian functions. MMPs are excreted by a variety of connective tissue and pro-inflammatory cells including fibroblasts, osteoblasts, endothelial cells, macrophages, neutrophils, and lymphocytes. These enzymes are expressed as zymogens, which are subsequently processed by other proteolytic enzymes (such as serine proteases, furin, plasmin, and others) to generate the active forms. Matrix metalloproteinases are considered as promising targets for the treatment of cancer due to their strong involvement in malignant pathologies. Clinical/preclinical studies on MMP inhibition in tumor models brought positive results raising the idea that the development of strategies to inhibit MMPs may be proved to be a powerful tool to fight against cancer. However, the presence of an inherent flexibility in the MMP active-site limits dramatically the accurate modeling of MMP-inhibitor complexes. The interest in the application of quantitative structure-activity relationships (QSARs) has steadily increased in recent decades and we hope it may be useful in elucidating the mechanisms of chemical-biological interactions for this enzyme. In the present review, an attempt has been made to explore the in-depth knowledge from the classification of this enzyme to the clinical trials of their inhibitors. A total number of 92 QSAR models (44 published and 48 new formulated QSAR models) have also been presented to understand the chemical-biological interactions. QSAR results on the inhibition of various compound series against MMP-1, -2, -3, -7, -8, -9, -12, -13, and -14 reveal a number of interesting points. The most important of these are hydrophobicity and molar refractivity, which are the most important determinants of the activity.

Abstract
The extracellular matrix is a dynamic environment that constantly undergoes remodelling and degradation during vital physiological processes such as angiogenesis, wound healing, and development. Unbalanced extracellular matrix breakdown is associated with many diseases such as arthritis, cancer and fibrosis. Interstitial collagen is degraded by matrix metalloproteinases with collagenolytic activity by MMP-1, MMP-8 and MMP-13, collectively known as the collagenases. Matrix metalloproteinase 1 (MMP-1) plays a pivotal role in degradation of interstitial collagen types I, II, and III. Here, we report the crystal structure of the active form of human MMP-1 at 2.67 Å resolution. This is the first MMP-1 structure that is free of inhibitor and a water molecule essential for peptide hydrolysis is observed coordinated with the active site zinc. Comparing this structure with the human proMMP-1 shows significant structural differences, mainly in the relative orientation of the hemopexin domain, between the pro form and active form of the human enzyme.

Abstract
Matrix metalloproteinases (MMPs) are a family of Zn-dependent endo-peptidases known for their ability to cleave several components of the extracellular matrix, but which can also cleave many non-matrix proteins. There are many evidences that MMPs are involved in physiological and pathological processes, and a huge effort has been put in the development of possible inhibitors that could reduce the activity of MMPs, as it is clear that the ability to monitor and control such activity plays a pivotal role in the search for potential drugs aimed at finding a cure for several diseases such as pulmonary emphysema, rheumatoid arthritis, fibrotic disorders and cancer.A powerful method currently available to study enzyme-inhibitor interactions is based on the use of the surface plasmon resonance (SPR) technique. When MMP interactions are studied, a procedure by which inhibitors are normally anchored on sensor chips and SPR technique is used in order to study their interaction with MMPs molecules is usually followed. This is because it is currently believed that MMPs cannot be anchored on the sensor-chip surface without losing their activity. However, this approach gives rise to problems, as the anchoring of low-molecular-weight inhibitors on gold surfaces easily affects their ability to interact with MMPs. For this reason, the anchoring of MMPs is highly desirable.A new experimental protocol that couples the Fourier transform-SPR (FT-SPR) technique with electrospray ionization-mass spectroscopy (ESI-MS) is described here for the evaluation of the activity of MMP-1 catalytic domain (cdMMP-1) anchored on gold surfaces. The cdMMP-1 surface coverage is calculated by using FT-SPR and the enzyme activity is estimated by ESI-MS. The proposed method is label-free.

Abstract
A combination of in silico tools and experimental NMR data is proposed for relatively fast determination of protein-ligand structural models and demonstrated from known inhibitors of matrix metalloproteinases (MMP). The 15N 1H heteronuclear single quantum coherence (HSQC) spectral assignment and the 3D structure, either X-ray or NMR, are needed. In this method, the HSQC spectrum with or without the ligand is used to determine the interaction region of the ligand. Docking calculations are then performed to obtain a set of structural models. From the latter, the nuclear Overhauser effects (NOEs) between the ligand and the protein can be predicted. Guided by these predictions, a number of NOEs can be detected and assigned through a HSQC NOESY experiment. These data are used as structural restraints to reject/refine the initial structural models through further in silico work. For a test protein (MMP-12, human macrophage metalloelastase), a final structure of a protein-ligand adduct was obtained that matches well with the full structural determination. A number of structural predictions were then made for adducts of a similar protein (MMP-1, human fibroblast collagenase) with the same and different ligands. The quality of the final results depended on the type and number of experimental NOEs, but in all cases, a well-defined ligand conformation in the protein binding site was obtained. This protocol is proposed as a viable alternative to the many approaches described in the literature.

Abstract
Matrix Metalloproteinases (MMPs) are a family of multidomain zinc endopeptidases that function in the extracellular space or attached to the cell membrane. Their proteolytic activity is controlled by the presence of endogenous inhibitors, the tissue inhibitors of matrix metalloproteinases (TIMPs), alpha-macroglobulin and others. Disruption of the proteinase-inhibitor balance is observed in serious diseases such as arthritis, tumor growth and metastasis, rendering the MMPs attractive targets for drug intervention by pharmacological inhibitors. The determination of MMP structures is of critical importance in order to understand their substrate preferences, dimerization events, and their association with matrix components and inhibitors. Thus, MMP structures may contribute significantly to the development of specific MMP inhibitors, which should allow precise control of individual members of the MMP family without affecting all members or the closely related metalloproteinases such as ADAMs and ADAMTSs.

Abstract
Hybrid Car-Parrinello QM/MM calculations are used to investigate the reaction mechanism of hydrolysis of a common beta-lactam substrate (cefotaxime) by the monozinc beta-lactamase from Bacillus cereus (BcII). The calculations suggest a fundamental role for an active site water in the catalytic mechanism. This water molecule binds the zinc ion in the first step of the reaction, expanding the zinc coordination number and providing a proton donor adequately oriented for the second step. The free energy barriers of the two reaction steps are similar and consistent with the available experimental data. The conserved hydrogen bond network in the active site, defined by Asp120, Cys221, and His263, not only contributes to orient the nucleophile (as already proposed), but it also guides the second catalytic water molecule to the zinc ion after the substrate is bound. The hydrolysis reaction in water has a relatively high free energy barrier, which is consistent with the stability of cefotaxime in water solution. The modeled Michaelis complexes for other substrates are also characterized by the presence of an ordered water molecule in the same position, suggesting that this mechanism might be general for the hydrolysis of different beta-lactam substrates.

Abstract
BaP1 is a 22.7-kD P-I-type zinc-dependent metalloproteinase isolated from the venom of the snake Bothrops asper, a medically relevant species in Central America. This enzyme exerts multiple tissue-damaging activities, including hemorrhage, myonecrosis, dermonecrosis, blistering, and edema. BaP1 is a single chain of 202 amino acids that shows highest sequence identity with metalloproteinases isolated from the venoms of snakes of the subfamily Crotalinae. It has six Cys residues involved in three disulfide bridges (Cys 117-Cys 197, Cys 159-Cys 181, Cys 157-Cys 164). It has the consensus sequence H(142)E(143)XXH(146)XXGXXH(152), as well as the sequence C(164)I(165)M(166), which characterize the "metzincin" superfamily of metalloproteinases. The active-site cleft separates a major subdomain (residues 1-152), comprising four alpha-helices and a five-stranded beta-sheet, from the minor subdomain, which is formed by a single alpha-helix and several loops. The catalytic zinc ion is coordinated by the N(epsilon 2) nitrogen atoms of His 142, His 146, and His 152, in addition to a solvent water molecule, which in turn is bound to Glu 143. Several conserved residues contribute to the formation of the hydrophobic pocket, and Met 166 serves as a hydrophobic base for the active-site groups. Sequence and structural comparisons of hemorrhagic and nonhemorrhagic P-I metalloproteinases from snake venoms revealed differences in several regions. In particular, the loop comprising residues 153 to 176 has marked structural differences between metalloproteinases with very different hemorrhagic activities. Because this region lies in close proximity to the active-site microenvironment, it may influence the interaction of these enzymes with physiologically relevant substrates in the extracellular matrix.

Abstract
Nephrosin is a newly discovered member of the astacin family. It is a secreted proteinase and is present in carp head kidney, kidney, and spleen, all of which are responsible for immune and hematopoietic functions in fish. A complex formed by nephrosin and its inhibitor was purified from carp kidney extract by heparin affinity column chromatography. The presence of the nephrosin-inhibitor complex in different tissues was examined by immunoblotting with polyclonal antisera against the purified nephrosin inhibitor and nephrosin. Both nephrosin and the nephrosin inhibitor were present mainly in gill, head kidney, kidney, and spleen. In addition, we have cloned the cDNA encoding the nephrosin inhibitor. There are two different cDNA clones possibly resulting from two different genes, and the long form contains unique tandem repeat sequences in the 3'-end. The deduced primary structure of nephrosin inhibitor is similar to that of fetuin-A, a mammalian protein present in blood, liver, cerebrospinal fluid, and cerebral cortex during fetal development. Treatment with both N-glycosidase F and O-glycosidase removed the carbohydrate moiety of the nephrosin inhibitor and decreased the apparent molecular mass from 40 to 30 kDa. The nephrosin inhibitor seems to be synthesized in liver and then secreted to the blood as a precursor. When it was distributed into hematopoietic tissues, it was processed from 67 to 40 kDa and acquired inhibitory activity. This processing phenomenon of fetuin has not been reported elsewhere. Importantly, the presence of an endogenous inhibitor of nephrosin is the first report of this kind for astacin enzymes. It is very likely that endogenous tissue inhibitors may also be present for the regulation of other astacin enzymes.

Abstract
Matrix metalloproteases (MMPs) are zinc endopeptidases deeply implicated in tumor progression. MMP inhibitors are attractive potential anti-cancer agent. Unfortunately, until now, clinical trials remain disappointing, that could be the result of a lack of selectivity. We propose second generation selective MMPs, directed toward gelatinase A (MMP-2), based on a non-hydroxamate Zn-ligand grafted on the galardin (ilomastat) skeleton.

Abstract
Here we report molecular dynamics (MD) and free energy perturbation (FEP) simulations applied to hydroxamate-matrix metalloproteinase-2 (MMP-2) complex systems. We have developed some new force field parameters for the hydroxamate functional group that were not included in the AMBER94 force field but were necessary in our simulations. For the representation of the active zinc center, a bonded model was adopted in which restrained electrostatic potential fitting (RESP) charges were used as the electrostatic representation of this model. Using the resulted bonded model, FEP simulations predict the relative binding free energy in good agreement with the experimental value. By analyzing the molecular dynamics (MD) trajectories of the two complex systems, we can provide an explanation of why one of the two inhibitors is favored over the other. The results provide a chemical insight into the interactions between inhibitor and enzyme, and can indicate changes in the inhibitor that would enhance inhibitor-enzyme interactions.

Abstract
Four series of tetradentate tripodal ligands containing pyridyl, 2-imidazolyl, 4-imidazolyl, amino, and/or carboxylic groups were synthesized as hydrolytic zinc enzyme models in order to elucidate the effect of various coordination environments on zinc binding and the acidity of zinc-bound water. In aqueous solution, ligands with same charges showed a good correlation between zinc binding (log K(ZnL)) and zinc-bound water acidity (pK(a) of LZnOH(2)); the stronger the zinc binding, the higher the pK(a). The zinc-bound water acidity decreased as pyridyl groups were replaced by carboxylate groups. However, exchanging amino groups for carboxylate groups gave no change in zinc-bound water acidity regardless of the charge of the atoms in the inner coordination sphere of the metal ion. The results are consistent with the conventional notion that negatively charged carboxylate groups inherently increase zinc binding and result in decreasing zinc-bound water acidity, but also suggest that environmental effects may modulate or dominate control of acidity.

Abstract
The effect of a range of metal ions on the ability of Marimastat to inhibit matrix metalloproteinase 9 (MMP-9) was examined in a fluorescence based proteolytic assay. Whilst none of the metals examined significantly affected the inhibitory ability of Marimastat, several metal ions did have a significant effect on MMP-9 activity itself. In the absence of Marimastat, Zn(II) and Fe(II) significantly inhibited MMP-9 activity at metal ion concentrations of 10 and 100 microM, respectively. In both the absence and presence of Marimastat, Cd(II) significantly inhibited MMP-9 at 100 microM. In contrast, 1 mM Co(II) significantly upregulated MMP-9 proteolytic activity.

The synthesis of several analogues of galardin, a MMP inhibitor, are presented with their in vitro inhibitory activity against MMP-1 and MMP-2. These compounds contain a distinct Zinc Binding Group (ZBG). Those having a 2-acylated-heterocycle as well as a 2-arylamide function do not exhibit a good inhibition/selectivity against the enzymes tested. On the contrary, those that are based on a hydrazide scaffold present potent selectivity for MMP-2 versus MMP-1.

Abstract
Side-chain flexibility of ligand-binding sites needs to be considered in the rational design of novel inhibitors. We have developed a method to generate conformational ensembles that efficiently sample local side-chain flexibility from a single crystal structure. The rotamer-based approach is tested here for the S1' pocket of human collagenase-1 (MMP-1), which is known to undergo conformational changes in multiple side-chains upon binding of certain inhibitors. First, a raw ensemble consisting of a large number of conformers of the S1' pocket was generated using an exhaustive search of rotamer combinations on a template crystal structure. A combination of principal component analysis and fuzzy clustering was then employed to successfully identify a core ensemble consisting of a low number of representatives from the raw ensemble. The core ensemble contained geometrically diverse conformers of stable nature, as indicated in several cases by a relative energy lower than that of the minimised template crystal structure. Through comparisons with X-ray crystallography and NMR structural data we show that the core ensemble occupied a conformational space similar to that observed under experimental conditions. The synthetic inhibitor RS-104966 is known to induce a conformational change in the side-chains of the S1' pocket of MMP-1 and could not be docked in the template crystal structure. However, the experimental binding mode was reproduced successfully using members of the core ensemble as the docking target, establishing the usefulness of the method in drug design.

Abstract
Malignant tumors express high levels of zinc-dependent endopeptidases called matrix metalloproteinases (MMPs), which are thought to facilitate tumor metastasis and angiogenesis by hydrolyzing components of the extracellular matrix. Of these enzymes, gelatinases A (MMP-2) and B (MMP-9), have especially been implicated in malignant processes, and thus, they have been a target for drugs designed to block their activity. Therefore, understanding their molecular structure is key for a rational approach to inhibitor design. Here, we have conducted x-ray absorption spectroscopy of the full-length human MMP-2 in its latent, active, and inhibited states and report the structural changes at the zinc ion site upon enzyme activation and inhibition. We have also examined the molecular structure of MMP-2 in complex with SB-3CT, a recently reported novel mechanism-based synthetic inhibitor that was designed to be highly selective in gelatinases. It is shown that SB-3CT directly binds the catalytic zinc ion of MMP-2. Interestingly, the novel mode of binding of the inhibitor to the catalytic zinc reconstructs the conformational environment around the active site metal ion back to that of the proenzyme.

Abstract
Stromelysin-3 (ST3) is a matrix metalloproteinase (MMP-11) whose proteolytic activity plays an important role in tumorigenicity enhancement. In breast cancer, ST3 is a bad prognosis marker: its expression is associated with a poor clinical outcome. This enzyme therefore represents an attractive therapeutic target. The topology of matrix metalloproteinases (MMPs) is remarkably well conserved, making the design of highly specific inhibitors difficult. The major difference between MMPs lies in the S(1)' subsite, a well-defined hydrophobic pocket of variable depth. The present crystal structure, the first 3D-structure of the ST3 catalytic domain in interaction with a phosphinic inhibitor mimicking a (d, l) peptide, clearly demonstrates that its S(1)' pocket corresponds to a tunnel running through the enzyme. This open channel is filled by the inhibitor P(1)' group which adopts a constrained conformation to fit this pocket, together with two water molecules interacting with the ST3-specific residue Gln215. These observations provide clues for the design of more specific inhibitors and show how ST3 can accommodate a phosphinic inhibitor mimicking a (d, l) peptide. The presence of a water molecule interacting with one oxygen atom of the inhibitor phosphinyl group and the proline residue of the Met-turn suggests how the intermediate formed during proteolysis may be stabilized. Furthermore, the hydrogen bond distance observed between the methyl of the phosphinic group and the carbonyl group of Ala182 mimics the interaction between this carbonyl group and the amide group of the cleaved peptidic bond. Our crystal structure provides a good model to study the MMPs mechanism of proteolysis.
