	2.6.1.3
Description	Cysteine aminotransferase
Catalyzed reaction	L-cysteine + 2-oxoglutarate = mercaptopyruvate + L-glutamate.
Cofactor	Pyridoxal-phosphate.
	In rat, there are evidences that that cytosolic cysteine aminotransferase is identical with cytosolic aspartate aminotransferase (EC 2.6.1.1). In bacteria, different aspartate aminotransferases (2.6.1.1) and aromatic amino acid aminotransferase (2.6.1.57) can transaminate L-Cysteine.
Organisms	-Eubacteria -Metazoa
