Broad specificity amino-acid racemase

UniProtKB accession:  A0KLG5

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Amino-acid racemase able to utilize a broad range of substrates. Reversibly racemizes ten of the 19 natural chiral amino acids known, including both non-beta-branched aliphatic amino acids (Ala, Leu, Met, Ser, Cys, Gln and Asn) and positively charged amino acids (His, Lys and Arg). Is not active on negatively charged (Glu and Asp) or aromatic (Tyr, Trp and Phe) amino acids and displays minimal activity towards beta-branched aliphatic (Ile, Val and Thr) substrates (PubMed:24419381). Enables bacteria to produce and release extracellular non-canonical D-amino acids (NCDAAs) that regulate diverse cellular processes (By similarity).
