General annotation (Comments)

Function	Important for the metabolism of amino acids and Krebs-cycle related organic acids. In plants, it is involved in nitrogen metabolism and in aspects of carbon and energy metabolism By similarity.
Catalytic activity	L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.
Cofactor	Pyridoxal phosphate By similarity.
Subunit structure	Homodimer By similarity. UniProtKB P28011
Miscellaneous	In eukaryotes there are cytoplasmic, mitochondrial and chloroplastic isozymes.
Sequence similarities	Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family.
