CC   -!- FUNCTION: Catalyzes the interconversion of L-alanine and D-alanine. May
CC       also act on other amino acids. {ECO:0000255|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: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-
