CC   -!- FUNCTION: Involved in the biosynthesis of alanine. Catalyzes the
CC       transamination of pyruvate by glutamate, leading to the formation of L-
CC       alanine and 2-oxoglutarate. Is also able to catalyze the reverse
CC       reaction. {ECO:0000250|UniProtKB:P0A959}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + L-alanine = L-glutamate + pyruvate;
CC         Xref=Rhea:RHEA:19453, ChEBI:CHEBI:15361, ChEBI:CHEBI:16810,
CC         ChEBI:CHEBI:29985, ChEBI:CHEBI:57972; EC=2.6.1.2;

CC         Evidence={ECO:0000250|UniProtKB:P0A959};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000250|UniProtKB:P0A959};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-alanine biosynthesis.
CC       {ECO:0000250|UniProtKB:P0A959}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P0A959}.
CC   -!- SIMILARITY: Belongs to the class-I pyridoxal-phosphate-dependent
CC       aminotransferase family. {ECO:0000305}.
