Aromatic L-amino acid decarboxylase: conformational change in the flexible region around Arg334 is required during the transaldimination process. (1/84)

Aromatic L-amino acid decarboxylase (AADC) catalytic mechanism has been proposed to proceed through two consecutive intermediates (i.e., Michaelis complex and the external aldimine). Limited proteolysis of AADC that preferentially digested at the C-terminal side of Arg334 was slightly retarded in the presence of dihydroxyphenyl acetate that formed a stable Michaelis complex. On the contrary, AADC was scarcely digested in the presence of L-dopa methyl ester that formed a stable external aldimine. Similar protection by the substrate analogs was observed in the chemical modification experiment. From these results, we concluded that the region around Arg334 must be exposed and flexible in the unliganded state, and forming the Michaelis complex generated a subtle conformational change, then underwent marked conformational change during the subsequent transaldimination process prerequisite to forming the external aldimine. For further analyses, we constructed a mutant gene encoding in tandem the two peptides of AADC cleaved at the Asn327-Met328 bond inside the putative flexible region. The gene product, fragmentary AADC, was still active with L-dopa as substrate, but its k(cat) value was decreased 57-fold, and the Km value was increased 9-fold compared with those of the wild-type AADC. The absorption spectra of the fragmentary AADC in the presence of L-dopa methyl ester showed shift in the equilibrium of the transaldimination from the external aldimine to the Michaelis complex. Tryptic digestion of the fragmentary AADC removed seven amino acid residues, Met328-Arg334, and resulted in complete inactivation. Susceptibility of the fragmentary enzyme to trypsin was not changed by L-dopa methyl ester revealing the loss of appropriate conformational change in the flexible region induced by substrate binding. From these results we propose that the conformational change in the flexible region is required during the transaldimination process.  (+info)

Role of tyrosine 265 of alanine racemase from Bacillus stearothermophilus. (2/84)

Tyrosine 265 (Y265) of Bacillus stearothermophilus is believed to serve as a catalytic base specific to the L-enantiomer of a substrate amino acid by removing (or returning) an alpha-hydrogen from (or to) the isomer on the basis of the X-ray structure of the enzyme [Stamper, C.G., Morollo, A.A., and Ringe, D. (1998) Biochemistry 37, 10438-10443]. We found that the Y265-->Ala mutant (Y265A) enzyme is virtually inactive as a catalyst for alanine racemization. We examined the role of Y265 further with beta-chloroalanine as a substrate with the expectation that the Y265A mutant only catalyzes the alpha,beta-elimination of the D-enantiomer of beta-chloroalanine. However, L-beta-chloroalanine also served as a substrate; this enantiomer was rather better as a substrate than its antipode. Moreover, the mutant enzyme was as equally active as the wild-type enzyme in the elimination reaction. These findings indicate that Y265 is essential for alanine racemization but not for beta-chloroalanine elimination.  (+info)

Transcriptional control of peptidoglycan precursor synthesis during sporulation in Bacillus sphaericus. (3/84)

Synthesis of enzymes functional in the synthesis of nucleotide precursors of peptidoglycan ceases upon initiation of sporulation in Bacillus sphaericus. During sporulation, two periods of synthesis of these enzymes occur. The first starts at spore septum formation and is conincident with forespore engulfment; it involves the synthesis of those enzymes required for making the precursor of vegetative-type peptidoglycan, including L-lysyl ligase but no mesodiaminopimelyl ligase. The second period occurs shortly before the appearance of cortex. It involves the synthesis of diaminopimelyl ligase and the other enzymes needed for making the precursor of cortical peptidoglycan, but not lysyl ligase. Both events are a consequence of derepression at the level of transcription. Neither period of synthesis occurs in asporogenous mutants whose morphological block is at the point of spore septum formation.  (+info)

Tyrosine 265 of alanine racemase serves as a base abstracting alpha-hydrogen from L-alanine: the counterpart residue to lysine 39 specific to D-alanine. (4/84)

Alanine racemase of Bacillus stearothermophilus has been proposed to catalyze alanine racemization by means of two catalytic bases: lysine 39 (K39) abstracting specifically the alpha-hydrogen of D-alanine and tyrosine 265 (Y265) playing the corresponding role for the antipode L-alanine. The role of K39 as indicated has already been verified [Watanabe, A., Kurokawa, Y., Yoshimura, T., Kurihara, T., Soda, K., and Esaki, N. (1999) J. Biol. Chem. 274, 4189-4194]. We here present evidence for the functioning of Y265 as the base catalyst specific to L-alanine. The Y265-->Ala mutant enzyme (Y265A), like Y265S and Y265F, was a poor catalyst for alanine racemization. However, Y265A and Y265S catalyzed transamination with D-alanine much more rapidly than the wild-type enzyme, and the bound coenzyme, pyridoxal 5'-phosphate (PLP), was converted to pyridoxamine 5'-phosphate (PMP). The rate of transamination catalyzed by Y265F was about 9% of that by the wild-type enzyme. However, Y265A, Y265S, and Y265F were similar in that L-alanine was inert as a substrate in transamination. The apo-form of the wild-type enzyme catalyzes the abstraction of tritium non-specifically from both (4'S)- and (4'R)-[4'-(3)H]PMP in the presence of pyruvate. In contrast, apo-Y265A abstracts tritium virtually from only the R-isomer. This indicates that the side-chain of Y265 abstracts the alpha-hydrogen of L-alanine and transfers it supra-facially to the pro-S position at C-4' of PMP. Y265 is the counterpart residue to K39 that transfers the alpha-hydrogen of D-alanine to the pro-R position of PMP.  (+info)

A eukaryotic alanine racemase gene involved in cyclic peptide biosynthesis. (5/84)

The cyclic tetrapeptide HC-toxin is an essential virulence determinant for the plant pathogenic fungus Cochliobolus carbonum and an inhibitor of histone deacetylase. The major form of HC-toxin contains the D-isomers of Ala and Pro. The non-ribosomal peptide synthetase that synthesizes HC-toxin has only one epimerizing domain for conversion of L-Pro to D-Pro; the source of D-Ala has remained unknown. Here we present the cloning and characterization of a new gene involved in HC-toxin biosynthesis, TOXG. TOXG is present only in HC-toxin-producing (Tox2(+)) isolates of C. carbonum. TOXG is able to support D-Ala-independent growth of a strain of Escherichia coli defective in D-Ala synthesis. A C. carbonum strain with both of its copies of TOXG mutated grows normally in culture, and although it no longer makes the three forms of HC-toxin that contain D-Ala, it still makes a minor form of HC-toxin that contains Gly in place of D-Ala. The addition of D-Ala to the culture medium restores production of the D-Ala-containing forms of HC-toxin by the toxG mutant. The toxG mutant has only partially reduced virulence. It is concluded that TOXG encodes an alanine racemase whose function is to synthesize D-Ala for incorporation into HC-toxin.  (+info)

Most progress has been made with the fold type I or aspartate aminotransferase family.  (+info)

Serine and alanine racemase activities of VanT: a protein necessary for vancomycin resistance in Enterococcus gallinarum BM4174. (7/84)

Vancomycin resistance in Enterococcus gallinarum results from the production of UDP-MurNAc-pentapeptide[D-Ser]. VanT, a membrane-bound serine racemase, is one of three proteins essential for this resistance. To investigate the selectivity of racemization of L-Ser or L-Ala by VanT, a strain of Escherichia coli TKL-10 that requires D-Ala for growth at 42 degrees C was used as host for transformation experiments using plasmids containing the full-length vanT from Ent. gallinarum or the alanine racemase gene (alr) of Bacillus stearothermophilus: both plasmids were able to complement E. coli TKL-10 at 42 degrees C. No alanine or serine racemase activities were detected in the host strain E. coli TKL-10 grown at 30, 34 or 37 degrees C. Serine and alanine racemase activities were found almost exclusively (96%) in the membrane fraction of E. coli TKL-10/pCA4(vanT): the alanine racemase activity of VanT was 14% of the serine racemase activity in both E. coli TKL-10/pCA4(vanT) and E. coli XL-1 Blue/pCA4(vanT). Alanine racemase activity was present mainly (95%) in the cytoplasmic fraction of E. coli TKL-10/pJW40(alr), with a trace (1.6%) of serine racemase activity. Additionally, DNA encoding the soluble domain of VanT was cloned and expressed in E. coli M15 as a His-tagged polypeptide and purified: this polypeptide also exhibited both serine and alanine racemase activities; the latter was approximately 18% of the serine racemase activity, similar to that of the full-length, membrane-bound enzyme. N-terminal sequencing of the purified His-tagged polypeptide revealed a single amino acid sequence, indicating that the formation of heterodimers between subunits of His-tagged C-VanT and endogenous alanine racemases from E. coli was unlikely. The authors conclude that the membrane-bound serine racemase VanT also has alanine racemase activity but is able to racemize serine more efficiently than alanine, and that the cytoplasmic domain is responsible for the racemase activity.  (+info)

Functional characterization of alanine racemase from Schizosaccharomyces pombe: a eucaryotic counterpart to bacterial alanine racemase. (8/84)

Schizosaccharomyces pombe has an open reading frame, which we named alr1(+), encoding a putative protein similar to bacterial alanine racemase. We cloned the alr1(+) gene in Escherichia coli and purified the gene product (Alr1p), with an M(r) of 41,590, to homogeneity. Alr1p contains pyridoxal 5'-phosphate as a coenzyme and catalyzes the racemization of alanine with apparent K(m) and V(max) values as follows: for L-alanine, 5.0 mM and 670 micromol/min/mg, respectively, and for D-alanine, 2.4 mM and 350 micromol/min/mg, respectively. The enzyme is almost specific to alanine, but L-serine and L-2-aminobutyrate are racemized slowly at rates 3.7 and 0.37% of that of L-alanine, respectively. S. pombe uses D-alanine as a sole nitrogen source, but deletion of the alr1(+) gene resulted in retarded growth on the same medium. This indicates that S. pombe has catabolic pathways for both enantiomers of alanine and that the pathway for L-alanine coupled with racemization plays a major role in the catabolism of D-alanine. Saccharomyces cerevisiae differs markedly from S. pombe: S. cerevisiae uses L-alanine but not D-alanine as a sole nitrogen source. Moreover, D-alanine is toxic to S. cerevisiae. However, heterologous expression of the alr1(+) gene enabled S. cerevisiae to grow efficiently on D-alanine as a sole nitrogen source. The recombinant yeast was relieved from the toxicity of D-alanine.  (+info)

AU - Kim, Eunice EunKyeong. AU - Hwang, Kwang Yeon. PY - 2009/7/1. Y1 - 2009/7/1. N2 - Alanine racemase (AlaR) is a bacterial enzyme that belongs to the fold-type III group of pyridoxal 5′-phosphate (PLP)-dependent enzymes. AlaR catalyzes the interconversion between l- and d-alanine, which is important for peptidoglycan biosynthesis. This enzyme is common in prokaryotes, but absent in eukaryotes, which makes it an attractive target for the design of new antibacterial drugs. Here, we report the crystal structures of both the apoenzyme and the d-cycloserine (DCS) complex of AlaR from the pathogenic bacterium Enterococcus faecalis v583, at a resolution of 2.5 Å. DCS is a suicide inhibitor of AlaR and, as such, serves as an antimicrobial agent and has been used to treat tuberculosis and urinary tract ...

A new immobilization method for enzymes is presented to facilitate synthetic applications in aqueous as well as organic media. The enzyme Alanine racemase (AlaR) from Geobacillus stearothermophilus was cloned, overexpressed and then immobilized on a silica-coated thin-layer chromatography plate to create an enzyme surface. The enzyme, fused to a His(6)-tag at its N-terminal, was tethered to the chemically modified silica-coated TLC plate through cobalt ions. The immobilized enzyme showed unaltered kinetic parameters in small-scale stirred reactions and retained its activity after rinsing, drying, freezing or immersion in n-hexane. This practical method is a first step towards a general immobilization method for synthesis applications with any enzyme suitable for His(6)-tagging.. ...

After transforming the exterior of the Minnehaha House, Nicole Curtis turns her attention to the interior where massive plumbing and electrical problems lurk behind the walls. Construction cannot start until the 100-year-old wiring and piping are up to code, and that means the little Sheetrock that is up must come down. At the same time, anxious to get started on cosmetic work, Nicole restores antique exterior sconces, and works with restoration experts to repair the glass window for the grand front door. When the lights finally go on and the water flows, the walls go up throughout the house and Nicole completes her entryway restoration.

Three C X bond formation mechanisms observed in the oxidation of (HBpz(3))ReO(R)(OTf) [HBpz(3) = hydrotris(1-pyrazolypborate; R = Me, Et, and iPr; OTf = OSO(2)CF(3)] by dimethyl sulfoxide (DMSO) were investigated using quantum mechanics (M06//B3LYP DFT) combined with solvation (using the PBF Poisson Boltzmann polarizable continuum solvent model). For R = Et we find the alkyl group is activated through alpha-hydrogen abstraction by external base OTf(-) with a free energy barrier of only 12.0 kcal/mol, leading to formation of acetaldehyde. Alternatively, ethyl migration across the M=O bond (leading to the formation of acetaldehyde and ethanol) poses a free energy barrier of 22.1 kcal/mol, and the previously proposed alpha-hydrogen transfer to oxo (a 2+2 forbidden reaction) poses a barrier of 44.9 kcal/mol. The rate-determining step to formation of the final product acetaldehyde is an oxygen atom transfer from DMSO to the ethylidene, with a free energy barrier of 15.3 kcal/mol. When R = iPr, the ...

Boss: Phogoth, the Untamed The final room contains Phogoth, who is initially chained up. The room also has multiple balconies with enemies on them, including Knights and Acolytes armed with Boomers. Players should take advantage of the situation and take out the Boomer-equipped enemies before engaging Phogoth, as he will not attack until he breaks free which will only happen if he is damaged. Players can hang back in the initial doorway, though a Shrieker will periodically spawn in that room, and Thralls and Knights will try to swarm them. The narrow doorway also makes it difficult to hit Phogoth without being exposed to its Eye Beam attack. The sides offer more protection than the entryway, though in a pinch Guardians can hide behind the narrow columns on the entryway balcony. Inside the room itself, Phogoth is partially penned in by large walls, three on either side. So long as players keep the walls between Phogoth and themselves, they are relatively safe from its Eye Beam attack. Stronger ...
Drug discovery and early to mid-stage drug development for HIV primarily takes place at academic institutions and small biotechnology companies. At the Frontiers in Developing Antiretroviral Therapy Conference (HIV DART 2014), which took place from December 9-12 in Miami, Florida, there were numerous presentations on promising new treatments for HIV being researched by academic institutions. One project that particularly stood out involved the development of early stage, dual-tropic HIV entry inhibitors that also inhibit HIV reverse transcriptase.. HIV entry into immune cells involves an initial interaction between the viral surface receptor, gp120, and the human cell surface receptor, CD4. This is followed by a subsequent interaction with one of two human cell surface co-receptors: CCR5 or CXCR4. CCR5 is the entryway for M-tropic viruses and CXCR4 is the entryway for T-tropic viruses. Tropism simply refers to the type of cell that HIV infects, and thus characterizes different HIV strains. ...

A unique d-to-l racemization of arginine by coupled arginine dehydrogenases DauA and DauB encoded by the dauBAR operon has been recently reported as a prerequisite for d-arginine utilization as the sole source of carbon and nitrogen through l-arginine catabolic pathways in P. aeruginosa. In this study, enzymic properties of the catabolic FAD-dependent d-amino acid dehydrogenase DauA and the physiological functions of the dauBAR operon were further characterized with other d-amino acids. These results establish DauA as a d-amino acid dehydrogenase of broad substrate specificity, with d-Arg and d-Lys as the two most effective substrates, based on the kinetic parameters. In addition, expression of dauBAR is specifically induced by exogenous d-Arg and d-Lys, and mutations in the dauBAR operon affect utilization of these two amino acids alone. The function of DauR as a repressor in the control of the dauBAR operon was demonstrated by dauB promoter activity measurements in vivo and mobility shift assays with
Lien vers Pubmed [PMID] - 23613764. PLoS ONE 2013;8(4):e60955. Chagas disease is caused by Trypanosoma cruzi, a protozoan transmitted to humans by blood-feeding insects, blood transfusion or congenitally. Previous research led us to discover a parasite proline racemase (TcPRAC) and to establish its validity as a target for the design of new chemotherapies against the disease, including its chronic form. A known inhibitor of proline racemases, 2-pyrrolecarboxylic acid (PYC), is water-insoluble. We synthesized soluble pyrazole derivatives, but they proved weak or inactive TcPRAC inhibitors. TcPRAC catalytic site is too small and constrained when bound to PYC to allow efficient search for new inhibitors by virtual screening. Forty-nine intermediate conformations between the opened enzyme structure and the closed liganded one were built by calculating a transition path with a method we developed. A wider range of chemical compounds could dock in the partially opened intermediate active site models ...
Catalyzes the oxidative deamination of D-amino acids. Has broad substrate specificity; is mostly active on D-alanine, and to a lesser extent, on several other D-amino acids such as D-methionine, D-serine and D-proline, but not on L-alanine. Participates in the utilization of L-alanine and D-alanine as the sole source of carbon, nitrogen and energy for growth. Is also able to oxidize D-amino acid analogs such as 3,4-dehydro-D-proline, D-2-aminobutyrate, D-norvaline, D-norleucine, cis-4-hydroxy-D-proline, and DL-ethionine.

There is a significant issue with aluminum in concrete - e.g., an aluminum post or conduit embedded in concrete is not a good idea. My hunch is that a piece of aluminum on top of already cured concrete will not have the same issues. However, I am not a metallurgist and so, to play it safe, I would look for a similar piece of steel instead.. On the other hand, a quick search finds steel thresholds to be a bit on the expensive side. I suggest checking with an aluminum threshold manufacturer to see if installation on top of concrete is acceptable.. ...

Salvaging Hurricane-Damaged Palms in the Nursery 2 dying. This may not be feasible for field nurseries without irrigation, but rainfall may be adequate to keep rootballs moist. If the trunk of a single-stemmed (versus clustering or clumping) palm is broken, whether completely severed at the base or anywhere along its length, splintered or sharply bent (kinked) at some point along its length -that palm is unredeemably damaged and cannot be save. Palm stems have no ability to heal as do broad-leaved trees. Clustering or clumping palms, however, continuously produce new stems and should not be removed, even if all the conspicuous, tall stems are badly damaged. Broken stems of a clustering palm should be carefully cut as close to their base as possible. Application of a fungicide after this operation is recommended, since the stumps can provide entryway for disease organisms. Even though a palm may have been left standing after the hurricanes passage, severe stresses to the crown and, most ...

The highlight for us was the last house we hit on the tour, the beautiful Victorian known as Idlewild, which just happens to be for sale. It was also the only multi-level home where we werent allowed upstairs, which was disappointing, plus I wasnt overwhelmed by the kitchen, but the rest of it was impressive as hell. The entryway is gorgeous and the wooden arch between the living room and dining room was absolutely stunning (the picture on the listing doesnt do it justice). I think The Brother was still kind of meh about it until we got outside and were directed to the wine cellar, which is only accessible from the side yard. I think that sold it for him. Probably a good thing he doesnt have a spare $1.7 million laying around. They also wisely didnt have any actual wine in there so we didnt have to fight off the temptation to make off with a souvenir ...

Wisdom tells me that happiness is temporary, fleeting. Happiness is a decision on how to react to the circumstances right in front of you. Teddy is an amazing example of reacting with either happiness or sadness to the thing that is right in front of his face. Last night when we picked up Teddy at my parents house, we brought everyone some chocolate chip cookies that we could all share together. We walked in my parents house through door off the garage and were greeted by Teddy (and Sophie the bop bop). Within seconds, Teddys gaze moved to cookies. He nodded vigorously, gasped excitedly, said Dees! Dees! (which seems to be an efficient combination of this, these and please), and sat right down on the floor in the entryway as if to say, Lets do this. Right here. Right now. We had not even shut the door behind us to come inside yet! Of course, we caved in and gave Teddy a cookie, but at least made him stand up and walk into the kitchen. His body wiggled with happiness, and he made grunts of ...

At the start of my tour, Margaret took me to her workshop, where she demonstrated how the Callanish stone circles were designed to be ellipses-not just poorly made circle-and how the stones were erected. She even let me hold a 4,000-year-old arrowhead-a tiny remnant of the prehistoric people who lived on this island. Mind-boggling!. Later, we ambled through Callanish I, the main stone ellipsis, which Margaret calls both a stone-age computer (because it marks solar and lunar events) and a community center (because it was a gathering place for singing, dancing, and burying the dead).. In a way, Callanish is still a community center-of World Heritage Site calibre. Over the days, I heard visitors from several continents speaking various languages, and I watched children have foot-races down the stone-lined avenue, the ancient entryway to the main circle. I saw photographers and artists capturing images of the stones on paper or in digital format. Couples paused to kiss. Baaing sheep gazed over ...
