Abstract
DMSP (dimethylsulfoniopropionate) is an ecologically important sulfur metabolite commonly produced by marine algae and by some higher plant lineages, including the polyploid salt marsh genus Spartina (Poaceae). The molecular mechanisms and genes involved in the DMSP biosynthesis pathways are still unknown. In this study, we performed comparative analyses of DMSP amounts and molecular phylogenetic analyses to decipher the origin of DMSP in Spartina that represents one of the major source of terrestrial DMSP in coastal marshes. DMSP content was explored in 14 Spartina species using 1H Nuclear Magnetic Resonance (NMR) spectroscopy and Ultra Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS). Putative genes encoding the four enzymatic steps of the DMSP biosynthesis pathway in Spartina were examined and their evolutionary dynamics were studied. We found that the hexaploid lineage containing S. alterniflora, S. foliosa and S. maritima and their derived hybrids and allopolyploids are all able to produce DMSP, in contrast to species in the tetraploid clade. Thus, examination of DMSP synthesis in a phylogenetic context implicated a single origin of this physiological innovation, which occurred in the ancestor of the hexaploid Spartina lineage, 3-6MYA. Candidate genes specific to the Spartina DMSP biosynthesis pathway were also retrieved from Spartina transcriptomes, and provide a framework for future investigations to decipher the molecular mechanisms involved in this plant phenotypic novelty that has major ecological impacts in saltmarsh ecosystems.

Abstract
Azospirillum brasilense belongs to the plant growth-promoting rhizobacteria with direct growth promotion through the production of the phytohormone indole-3-acetic acid (IAA). A key gene in the production of IAA, annotated as indole-3-pyruvate decarboxylase (ipdC), has been isolated from A. brasilense, and its regulation was reported previously (A. Vande Broek, P. Gysegom, O. Ona, N. Hendrickx, E. Prinsen, J. Van Impe, and J. Vanderleyden, Mol. Plant-Microbe Interact. 18:311-323, 2005). An ipdC-knockout mutant was found to produce only 10% (wt/vol) of the wild-type IAA production level. In this study, the encoded enzyme is characterized via a biochemical and phylogenetic analysis. Therefore, the recombinant enzyme was expressed and purified via heterologous overexpression in Escherichia coli and subsequent affinity chromatography. The molecular mass of the holoenzyme was determined by size-exclusion chromatography, suggesting a tetrameric structure, which is typical for 2-keto acid decarboxylases. The enzyme shows the highest kcat value for phenylpyruvate. Comparing values for the specificity constant kcat/Km, indole-3-pyruvate is converted 10-fold less efficiently, while no activity could be detected with benzoylformate. The enzyme shows pronounced substrate activation with indole-3-pyruvate and some other aromatic substrates, while for phenylpyruvate it appears to obey classical Michaelis-Menten kinetics. Based on these data, we propose a reclassification of the ipdC gene product of A. brasilense as a phenylpyruvate decarboxylase (EC 4.1.1.43).

Abstract
Arginine decarboxylase (ADC) and ornithine decarboxylase (ODC) are involved in the biosynthesis of putrescine, which is the precursor of other polyamines in animals, plants, and bacteria. These pyridoxal-5'-phosphate-dependent decarboxylases belong to the alanine racemase (AR) structural family together with diaminopimelate decarboxylase (DapDC), which catalyzes the final step of lysine biosynthesis in bacteria. We have constructed a multiple-sequence alignment of decarboxylases in the AR structural family and, based on the alignment, inferred phylogenetic trees. The phylogenetic tree consists of 3 distinct clades formed by ADC, DapDC, and ODC that diverged from an ancestral decarboxylase. The ancestral decarboxylase probably was able to recognize several substrates, and in archaea and bacteria, ODC may have retained the ability to bind other amino acids. Previously, a paralogue of ODC has been proposed to account for ADC activity detected in mammalian cells. According to our results, this appears unlikely, emphasizing the need for more caution in functional assignment made using sequence data and illustrating the continuing value of phylogenetic analysis in clarifying relationships and putative functions.

Abstract
AAA+ ATPases are ubiquitous proteins that employ the energy obtained from ATP hydrolysis to remodel proteins, DNA, or RNA. The MoxR family of AAA+ proteins is widespread throughout bacteria and archaea but is largely uncharacterized. Limited work with specific members has suggested a potential role as molecular chaperones involved in the assembly of protein complexes. As part of an effort aimed at determining the function of novel AAA+ chaperones in Escherichia coli, we report the characterization of a representative member of the MoxR family, YieN, which we have renamed RavA (regulatory ATPase variant A). We show that the ravA gene exists on an operon with another gene encoding a protein, YieM, of unknown function containing a Von Willebrand Factor Type A domain. RavA expression is under the control of the sigmaS transcription factor, and its levels increase toward late log/early stationary phase, consistent with its possible role as a general stress-response protein. RavA functions as an ATPase and forms hexameric oligomers. Importantly, we demonstrate that RavA interacts strongly with inducible lysine decarboxylase (LdcI or CadA) forming a large cage-like structure consisting of two LdcI decamers linked by a maximum of five RavA oligomers. Surprisingly, the activity of LdcI does not appear to be affected by binding to RavA in a number of in vitro and in vivo assays, however, complex formation results in the stimulation of RavA ATPase activity. Data obtained suggest that the RavA-LdcI interaction may be important for the regulation of RavA activity against its targets.

Abstract
Bacterial non-oxidative, reversible multi subunit hydroxyarylic acid decarboxylases/phenol carboxylases are encoded by the three clustered genes, B, C, and D, of approximately 0.6, 1.4, and 0.2 kb, respectively. There are more than 160 homologues in the database with significant similarity to gene B (homology to ubiX) and C (ubiD) distributed in all three microbial domains, however, homologues to gene D, are not numerous ( approximately 15). The occurrence of the entire BCD gene cluster encoding for either identified or presumptive hydroxyarylic acid decarboxylase to date has been revealed in Sedimentibacter hydroxybenzoicus (unique genes arrangement CDB), Streptomyces sp. D7, Bacillus subtilis, B. licheniformis, E. coli O157:H7, Klebsiella pneumoniae, Enterobacter cloacae, Shigella dysenteriae, Salmonella enterica, S. paratyphi, S. typhimurium, S. bongori, and S. diarizonae. The corresponding genes from S. hydroxybenzoicus, B. subtilis, Streptomyces sp. D7, E. coli O157:H7, K. pneumoniae, and S. typhimurium were cloned and expressed in E. coli DH5alpha (void of analogous genes), and shown to code for proteins exhibiting non-oxidative hydroxyarylic acid decarboxylase activity.

Abstract
Malic enzyme is a tetrameric protein with double dimer structure in which the dimer interface is more intimately contacted than the tetramer interface. Each monomeric unit of the enzyme is composed of four structural domains, which show a different folding topology from those of the other oxidative decarboxylases. The active center is located at the interface between domains B and C. For human mitochondrial malic enzyme, there is an exo nucleotide-binding site for the inhibitor ATP and an allosteric site for the activator fumarate, located at the tetramer and dimer interfaces, respectively. Crystal structures of the enzyme in various complexed forms indicate that the enzyme may exist in equilibrium among two open and two closed forms. Interconversion among these forms involves rigid-body movements of the four structural domains. Substrate binding at the active site shifts the open form to the closed form that represents an active site closure. Fumarate binding at the allosteric site induces the interconversion between forms I and II, which is mediated by the movements of domains A and D. Structures of malic enzyme from different sources are compared with an emphasis on the differences and their implications to structure-function relationships. The binding modes of the substrate, product, cofactors, and transition-state analogue at the active site, as well as ATP and fumarate at the exo site and allosteric site, respectively, provide a clear account for the catalytic mechanism, nucleotide specificities, allosteric regulation, and functional roles of the quaternary structure. The proposed catalytic mechanism involves tyrosine-112 and lysine-183 as the general acid and base, respectively. In addition, a divalent metal ion (Mn(2+) or Mg(2+)) is essential in helping the catalysis. Binding of the metal ion also plays an important role in stabilizing the quaternary structural integrity of the enzyme.

Abstract
Lysine decarboxylase (LDC; EC 4.1.1.18) from Selenomonas ruminantium comprises two identical monomeric subunits of 43 kDa and has decarboxylating activities toward both L-lysine and L-ornithine with similar K(m) and V(max) values (Y. Takatsuka, M. Onoda, T. Sugiyama, K. Muramoto, T. Tomita, and Y. Kamio, Biosci. Biotechnol. Biochem. 62:1063-1069, 1999). Here, the LDC-encoding gene (ldc) of this bacterium was cloned and characterized. DNA sequencing analysis revealed that the amino acid sequence of S. ruminantium LDC is 35% identical to those of eukaryotic ornithine decarboxylases (ODCs; EC 4.1.1.17), including the mouse, Saccharomyces cerevisiae, Neurospora crassa, Trypanosoma brucei, and Caenorhabditis elegans enzymes. In addition, 26 amino acid residues, K69, D88, E94, D134, R154, K169, H197, D233, G235, G236, G237, F238, E274, G276, R277, Y278, K294, Y323, Y331, D332, C360, D361, D364, G387, Y389, and F397 (mouse ODC numbering), all of which are implicated in the formation of the pyridoxal phosphate-binding domain and the substrate-binding domain and in dimer stabilization with the eukaryotic ODCs, were also conserved in S. ruminantium LDC. Computer analysis of the putative secondary structure of S. ruminantium LDC showed that it is approximately 70% identical to that of mouse ODC. We identified five amino acid residues, A44, G45, V46, P54, and S322, within the LDC catalytic domain that confer decarboxylase activities toward both L-lysine and L-ornithine with a substrate specificity ratio of 0.83 (defined as the k(cat)/K(m) ratio obtained with L-ornithine relative to that obtained with L-lysine). We have succeeded in converting S. ruminantium LDC to form with a substrate specificity ratio of 58 (70 times that of wild-type LDC) by constructing a mutant protein, A44V/G45T/V46P/P54D/S322A. In this study, we also showed that G350 is a crucial residue for stabilization of the dimer in S. ruminantium LDC.

Abstract
Cysteine sulfinate decarboxylase (CSD), the putative biosynthetic enzyme for taurine, was purified 1,800-fold with a 1% yield from rat liver, where it was found to be 20-fold enriched compared with brain. The final fraction was homogeneous, as ascertained through sodium dodecyl sulfate-polyacrylamide gel electrophoresis and reverse-phase HPLC. An antiserum was raised in the rabbit that (a) quantitatively immunoprecipitated CSD activity and (b) immunolabeled only one band (MW = 51,000) on an immunoblot from liver homogenate. Monoclonal antibodies were also raised that recognized the CSD protein and immunolabeled the same 51-kilodalton protein on an immunoblot from liver homogenate. In a brain extract, two CSD activities had been previously found and named CSDI and CSDII, according to their chromatographic elution patterns. We have compared the properties of CSDI from brain--the most likely enzyme involved in the biosynthesis of taurine in the brain, according to previous investigations-and CSD from liver: Both activities (a) were similarly eluted on ion-exchange and hydroxyapatite chromatographies, (b) showed the same elution pattern on gel filtration with an apparent native molecular weight of approximately 63,000, and (c) were immunoprecipitated in a strictly identical manner by the antiserum against liver CSD. Moreover, this antiserum as well as the monoclonal antibodies immunolabeled a single band (51 kilodaltons) on an immunoblot from brain CSD-enriched fraction or liver fraction. All these data show that CSDI from brain and liver CSD are the same monomeric enzyme. They also indicate that a specific antiserum against rat liver CSD has been raised that can be used for immunocytochemical visualization of CSD-containing cells in the brain.
