This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-cysteine:2-oxoglutarate aminotransferase. Other names in common use include cysteine aminotransferase, L-cysteine aminotransferase, and CGT. This enzyme participates in cysteine metabolism. It employs one cofactor, pyridoxal phosphate.
