CC         Rule:MF_01201};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000256|ARBA:ARBA00001933, ECO:0000256|HAMAP-
CC         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.
