CC ChEBI:CHEBI:57416, ChEBI:CHEBI:57972; EC=5.1.1.1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01201};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01201};
CC -!- PATHWAY: Amino-acid biosynthesis; D-alanine biosynthesis; D-alanine
CC from L-alanine: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01201}.
CC -!- SIMILARITY: Belongs to the alanine racemase family. {ECO:0000255|HAMAP-
CC Rule:MF_01201}.
