CC   -!- FUNCTION: Important for the metabolism of amino acids and Krebs-cycle
CC       related organic acids. In plants, it is involved in nitrogen metabolism
CC       and in aspects of carbon and energy metabolism.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + L-aspartate = L-glutamate + oxaloacetate;
CC         Xref=Rhea:RHEA:21824, ChEBI:CHEBI:16452, ChEBI:CHEBI:16810,
CC         ChEBI:CHEBI:29985, ChEBI:CHEBI:29991; EC=2.6.1.1;
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix.
CC   -!- MISCELLANEOUS: In eukaryotes there are cytoplasmic, mitochondrial and
CC       chloroplastic isozymes.
CC   -!- SIMILARITY: Belongs to the class-I pyridoxal-phosphate-dependent
CC       aminotransferase family. {ECO:0000305}.
