CC -!- FUNCTION: Catalyzes the interconversion of L-alanine and D-alanine. May
CC also act on other amino acids. {ECO:0000256|HAMAP-Rule:MF_01201}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-alanine = D-alanine; Xref=Rhea:RHEA:20249,
CC ChEBI:CHEBI:57416, ChEBI:CHEBI:57972; EC=5.1.1.1;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01201};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|HAMAP-Rule:MF_01201, ECO:0000256|PIRSR:PIRSR600821-50};
CC -!- PATHWAY: Amino-acid biosynthesis; D-alanine biosynthesis; D-alanine
CC from L-alanine: step 1/1. {ECO:0000256|HAMAP-Rule:MF_01201}.
CC -!- SIMILARITY: Belongs to the alanine racemase family. {ECO:0000256|HAMAP-
CC Rule:MF_01201}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
