Alanine Racemase (Crude Enzyme)
This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on aminoacids and derivatives. This enzyme participates in alanine and aspartatemetabolism and D-alanine metabolism. It employs one cofactor, pyridoxal phosphate. At least two compounds, 3-Fluoro-D-alanine and D-Cycloserine are known to inhibit this enzyme. The D-alanine produced by alanine racemase is used for peptidoglycan biosynthesis. Peptidoglycan is found in the cell walls of all bacteria, including many which are harmful to humans. The enzyme is absent in higher eukaryotes but found everywhere in prokaryotes, making alanine racemase a great target for antimicrobial drug...udies have shown that without the alr gene being expressed, the bacteria would need an external source of D-alanine in order to survive. Therefore, the alr gene is a feasible target for antimicrobial drugs. This product with the indicated enzyme activity was briefly purified from engineered E. coli. Applications: Drug development; pharmacology; medicine; pharmacology. Group: Enzymes. Synonyms: L-alanine racemase. Enzyme Commission Number: EC 5.1.1.1. CAS No. 9024-06-0. Alanine Racemase. Activity: Undetermined. Appearance: Clear to translucent yellow solution. Storage: at -20 °C or lower, for at least 1 month. Source: E. coli. L-alanine racemase. Pack: 100ml. Cat No: NATE-1854.
D-aspartate ligase
This enzyme forms part of the peptidoglycan assembly pathway of Gram-positive bacteria grown in medium containing D-Asp. Normally, the side chains the acylate the 6-amino group of the L-lysine residue contain L-Ala-L-Ala but these aminoacids are replaced by D-Asp when D-Asp is included in the medium. Hybrid chains containing L-Ala-D-Asp, L-Ala-L-Ala-D-Asp or D-Asp-L-Ala are not formed. The enzyme belongs in the ATP-grasp protein superfamily. The enzyme is highly specific for D-aspartate, as L-aspartate, D-glutamate, D-alanine, D-iso-asparagine and D-malic acid are not substrates. In Enterococcus faecium, the substrate D-aspartate is produced by EC 5.1.1.13, aspartate racemase. Group: Enzymes. Synonyms: Aslfm; UDP-MurNAc-pentapeptide:D-aspartate ligase; D-aspartic acid-activating enzyme. Enzyme Commission Number: EC 6.3.1.12. Storage: Store it at +4 ?C for short term.

hydantoin racemase
This enzyme, along with N-carbamoylase (EC 3.5.1.77 and EC 3.5.1.87) and hydantoinase, forms part of the reaction cascade known as the "hydantoinase process", which allows the total conversion of D,L-5-monosubstituted hydantoins into optically pure D- or L-aminoacids.

phenylalanine racemase (ATP-hydrolysing)
The enzyme phenylalanine racemase is the enzyme that acts on aminoacids and derivatives. It activates both the L & D stereo isomers of phenylalanine to form L-phenylalanyl adenylate and D-phenylalanyl adenylate, which are bound to the enzyme. These bound compounds are then transferred to the thiol group of the enzyme followed by conversion of its configuration, the D-isomer being the more favorable configuration of the two, with a 7 to 3 ratio between the two isomers. The racemisation reaction of phenylalanine is coupled with the highly favorable hydrolysis of adenosine triphosphate (ATP) to adenosine monophosphate (AMP) and pyrophosphate (PP), thermodynamically allowing it to proceed. This reaction is then drawn forward by further hydrolyzing PP to inorganic phosphate (Pi), via Le Chatelier's principle. Group: Enzymes. Synonyms: phenylalanine racemase; phenylalanine racemase (adenosine triphosphate-hydrolysing); gramicidin S synthetase I. Enzyme Commission Number: EC 5.1.1.11. CAS No. 37290-95-2.
