Abstract
This study investigated the effect of polycationic and uncharged polymers (and oligomers) on the catalytic parameters and thermostability of L-asparaginase from Thermococcus sibiricus (TsA). This enzyme has potential applications in the food industry to decrease the formation of carcinogenic acrylamide during the processing of carbohydrate-containing products. Conjugation with the polyamines polyethylenimine and spermine (PEI and Spm) or polyethylene glycol (PEG) did not significantly affect the secondary structure of the enzyme. PEG contributes to the stabilization of the dimeric form of TsA, as shown by HPLC. Furthermore, neither polyamines nor PEG significantly affected the binding of the L-Asn substrate to TsA. The conjugates showed greater maximum activity at pH 7.5 and 85 °C, 10-50% more than for native TsA. The pH optima for both TsA-PEI and TsA-Spm conjugates were shifted to lower pH ranges from pH 10 (for the native enzyme) to pH 8.0. Additionally, the TsA-Spm conjugate exhibited the highest activity at pH 6.5-9.0 among all the samples. Furthermore, the temperature optimum for activity at pH 7.5 shifted from 90-95 °C to 80-85 °C for the conjugates. The thermal inactivation mechanism of TsA-PEG appeared to change, and no aggregation was observed in contrast to that of the native enzyme. This was visually confirmed and supported by the analysis of the CD spectra, which remained almost unchanged after heating the conjugate solution. These results suggest that TsA-PEG may be a more stable form of TsA, making it a potentially more suitable option for industrial use.

Abstract
The rapid increase in the antibiotic resistance of microorganisms, capable of causing diseases in humans as destroying cultural heritage sites, is a great challenge for modern science. In this regard, it is necessary to develop fundamentally novel and highly active compounds. In this study, a series of N4-alkylcytidines, including 5- and 6-methylcytidine derivatives, with extended alkyl substituents, were obtained in order to develop a new generation of antibacterial and antifungal biocides based on nucleoside derivatives. It has been shown that N4-alkyl 5- or 6-methylcytidines effectively inhibit the growth of molds, isolated from the paintings in the halls of the Ancient Russian Paintings of the State Tretyakov Gallery, Russia, Moscow. The novel compounds showed activity similar to antiseptics commonly used to protect works of art, such as benzalkonium chloride, to which a number of microorganisms have acquired resistance. It was also shown that the activity of N4-alkylcytidines is comparable to that of some antibiotics used in medicine to fight Gram-positive bacteria, including resistant strains of Staphylococcus aureus and Mycobacterium smegmatis. N4-dodecyl-5- and 6-methylcytidines turned out to be the best. This compound seems promising for expanding the palette of antiseptics used in painting, since quite often the destruction of painting materials is caused by joint fungi and bacteria infection.

Abstract
The emergence of drug-resistant strains of pathogenic microorganisms necessitates the creation of new drugs. A series of uridine derivatives containing an extended substituent at the C-5 position as well as C-5 alkyloxymethyl, alkylthiomethyl, alkyltriazolylmethyl, alkylsulfinylmethyl and alkylsulfonylmethyl uridines were obtained in order to explore their antimicrobial properties and solubility. It has been shown that new ribonucleoside derivatives have an order of magnitude better solubility in water compared to their 2'-deoxy analogues and effectively inhibit the growth of a number of Gram-positive bacteria, including resistant strains of Mycobacterium smegmatis (MIC=15-200 μg/mL) and Staphylococcus aureus (MIC=25-100 μg/mL). Their activity is comparable to that of some antibiotics used in medicine.

Abstract
Filamentous fungi are one of the most important producers of secondary metabolites. Some of them can have a toxic effect on the human body, leading to diseases. On the other hand, they are widely used as pharmaceutically significant drugs, such as antibiotics, statins, and immunosuppressants. A single fungus species in response to various signals can produce 100 or more secondary metabolites. Such signaling is possible due to the coordinated regulation of several dozen biosynthetic gene clusters (BGCs), which are mosaically localized in different regions of fungal chromosomes. Their regulation includes several levels, from pathway-specific regulators, whose genes are localized inside BGCs, to global regulators of the cell (taking into account changes in pH, carbon consumption, etc.) and global regulators of secondary metabolism (affecting epigenetic changes driven by velvet family proteins, LaeA, etc.). In addition, various low-molecular-weight substances can have a mediating effect on such regulatory processes. This review is devoted to a critical analysis of the available data on the "turning on" and "off" of the biosynthesis of secondary metabolites in response to signals in filamentous fungi. To describe the ongoing processes, the model of "piano regulation" is proposed, whereby pressing a certain key (signal) leads to the extraction of a certain sound from the "musical instrument of the fungus cell", which is expressed in the production of a specific secondary metabolite.

Abstract
The high-yielding production of pharmaceutically significant secondary metabolites in filamentous fungi is obtained by random mutagenesis; such changes may be associated with shifts in the metabolism of polyamines. We have previously shown that, in the Acremonium chrysogenum cephalosporin C high-yielding strain (HY), the content of endogenous polyamines increased by four- to five-fold. Other studies have shown that the addition of exogenous polyamines can increase the production of target secondary metabolites in highly active fungal producers, in particular, increase the biosynthesis of β-lactams in the Penicillium chrysogenum Wis 54-1255 strain, an improved producer of penicillin G. In the current study, we demonstrate that the introduction of exogenous polyamines, such as spermidine or 1,3-diaminopropane, to A. chrysogenum wild-type (WT) and HY strains, leads to an increase in colony germination and morphological changes in a complete agar medium. The addition of 5 mM polyamines during fermentation increases the production of cephalosporin C in the A. chrysogenum HY strain by 15-20% and upregulates genes belonging to the beta-lactam biosynthetic cluster. The data obtained indicate the intersection of the metabolisms of polyamines and beta-lactams in A. chrysogenum and are important for the construction of improved producers of secondary metabolites in filamentous fungi.

Abstract
The emergence of drug-resistant strains of pathogenic microorganisms necessitates the creation of new drugs. In order to find new compounds that effectively inhibit the growth of pathogenic bacteria and fungi, we synthesized a set of N4-derivatives of cytidine, 2'-deoxycytidine and 5-metyl-2'-deoxycytidine bearing extended N4-alkyl and N4-phenylalkyl groups. The derivatives demonstrate activity against a number of Gram-positive bacteria, including Mycobacterium smegmatis (MIC = 24-200 μM) and Staphylococcus aureus (MIC = 50-200 μM), comparable with the activities of some antibiotics in medical use. The most promising compound appeared to be N4-dodecyl-5-metyl-2'-deoxycytidine 4h with activities of 24 and 48 μM against M. smegmatis and S. aureus, respectively, and high inhibitory activity of 0.5 mM against filamentous fungi that can, among other things, damage works of art, such as tempera painting. Noteworthy, some of other synthesized compounds are active against fungal growth with the inhibitory concentration in the range of 0.5-3 mM.

Abstract
The biogenic polyamines, spermine, spermidine (Spd) and putrescine (Put) are present at micro-millimolar concentrations in eukaryotic and prokaryotic cells (many prokaryotes have no spermine), participating in the regulation of cellular proliferation and differentiation. In mammalian cells Put is formed exclusively from L-ornithine by ornithine decarboxylase (ODC) and many potent ODC inhibitors are known. In bacteria, plants, and fungi Put is synthesized also from agmatine, which is formed from L-arginine by arginine decarboxylase (ADC). Here we demonstrate that the isosteric hydroxylamine analogue of agmatine (AO-Agm) is a new and very potent (IC50 3•10-8 M) inhibitor of E. coli ADC. It was almost two orders of magnitude less potent towards E. coli ODC. AO-Agm decreased polyamine pools and inhibited the growth of DU145 prostate cancer cells only at high concentration (1 mM). Growth inhibitory analysis of the Acremonium chrysogenum demonstrated that the wild type (WT) strain synthesized Put only from L-ornithine, while the cephalosporin C high-yielding strain, in which the polyamine pool is increased, could use both ODC and ADC to produce Put. Thus, AO-Agm is an important addition to the set of existing inhibitors of the enzymes of polyamine biosynthesis, and an important instrument for investigating polyamine biochemistry.

Abstract
An enzyme of cephalosporin-acid synthetase produced by the E. coli strain VKPM B-10182 has specificity for the synthesis of β-lactam antibiotics of the cephalosporin acids class (cefazolin, cefalotin, cefezole etc.). A comparison of the previously determined genomic sequence of E. coli VKPM B-10182 with a genome of the parent E. coli strain ATCC 9637 was performed. Multiple mutations indicating the long selection history of the strain were detected, including mutations in the genes of RNase and β-lactamases that could enhance the level of enzyme synthesis and reduce the degree of degradation of the synthesized cephalosporin acids. The CASA gene--a direct homolog of the penicillin G-acylase gene--was identified by bioinformatics methods. The homology of the gene was confirmed by gene cloning and the expression and determination of its enzymatic activity in the reaction of cefazolin synthesis. The CASA gene was isolated and cloned into the original expression vector, resulting in an effective E. coli BL2l(DE3) pMD0107 strain producing CASA.

Abstract
Vectors for the expression of the CefT transporter of the MFS family in Acremonium chrysogenum--a producer of beta-lactam antibiotic cephalosporin C--and in Saccharomyces cerevisiae as a fusion with the cyan fluorescent protein (CFP) have been created. The subcellular localization of the CefT-CFP hybrid protein in yeast cells has been investigated. It was shown that the CefT-CFP hybrid protein is capable of complementation of the qdr3, tpo 1, and tpo3 genes encoding for orthologous MFS transporters of Saccharomycetes, making the corresponding strains resistant to spermidine, ethidium bromide, and hygromycin B. High-yield strain VKM F-4081D of A. chrysogenum, expressing the cefT-cfp fusion, was obtained by an agrobacteria conjugated transfer. It was also shown that the constitutive expression of cefT in A. chrysogenum VKM F-4081D led to a change in the biosynthetic profiles of cephalosporin C and its precursors. This resulted in a 25-35% decrease in the finite product accumulated in the cultural liquid with a simultaneous increase in the concentration of its intermediators.

Abstract
Using pulse electrophoresis in controlled homogenous electric field we conducted molecular karyotyping of highly-productive and laboratory strains of Acremonium chrysogenum generating antibiotic cephalosporin C (cefC). Differences in size of several chromosomes of highly active strain CB26/8 compared to the wild-type strain ATCC 11550 were revealed. It was shown that chromosomal polymorphism in the highly active strain was not associated with alteration of localization and copy number ofcephalosporin C biosynthesis and transport genes. A cluster of "early" cefC biosynthesis genes is located on chromosome VI (4.4 Mb); a cluster of the "late genes", on chromosome II (2.3 Mb). Both clusters are presented as a single copy perA. chrysogenum genome in the wild-type and in CB26/8 producer strains. Based on comparative analysis of laboratory and industrial cefC producers, a karyotype scheme for A. chrysogenum strains of various origins was designed.

Abstract
The system of transformation of heterologous genes under the method of agrobacterial transfer into Acremonium chrysogenum ATCC 11550 wild-type strains, natural producents of beta-lactam antibiotic cephalosporin C, and strains highly producing cephalosporin C 26/8 revealed by the multistage selection on its basis were developed. Vectors for agrobacterial transformation of A. chrysogenum containing expression cassettes of genes encoding resistance to geneticin (G418) and bleomicin (Zeocin) antibiotics under control of Ashbya gossypii and Saccharomyces cerevisiae TEF1 promoters were constructed. A comparable assessment of agrotransformation methods while co-cultivating fungi and agrobacterial cells on filters and in deep culture was conducted. Transformants, selected by resistance to geneticin and bleomicin, were characterized by PCR and Southern blot analyses.

Abstract
The expression levels of cytochrome P450 2B4 variants with N- and C-terminal modifications were compared and some of the enzymatic characteristics of recombinant proteins studied. Following C-terminal hybrids for CYP2B4 gene were constructed: 1) with intein-chitin binding domain cassette 2) with hexahistidine tag. These modifications were combined with P450 2B4 glutathione-S-transferase N-terminal fusions [Pernecky S.J., et. al., (1995) Arch. Biochem. Biophys., 318, 446-456]. The obtained constructs provided for the synthesis of full-length protein products in E. coli cells with holoenzyme yield at the levels of 200-1000 nmoles/l of the bacterial culture. Partial in vivo proteolysis was observed for C-terminal fusions with intein moiety despite the presence of glycine aminoacid residue at the junction of two proteins. The principle inapplicability of standard purification scheme for isolation of P450 2B4-intein fusions is demonstrated, since the P450 domain is inactivated at 40 mM DTT concentrations. The recombinant full-length CYP 2B4 with C-terminal oligohistidine tail was expressed under the control of T7 promoter and purified using immobilized metal-ion chelating chromatography. The C-terminal hexahistidine tag does not affect the catalytic properties of recombinant enzyme in 7-pentoxyresorufin O-dealkylation reaction.

Abstract
One of the most exact methods of diagnosing disturbed absorption is perfusion of the small intestine. To make pertinent investigations a special perfusion probe manufactured of a roentgen-contrast rubber and a peristaltic pump for introducing a perfusion solution into the lumen of the intestine are proposed. A procedure used in conducting the examination is described and a formula for determining the absorption rate is given.
