Branched-chain amino acid aminotransferase (BCAT)

Definition:

Branched-chain amino acid aminotransferases (BCATs) catalyze reversible stereoselective transamination of branched-chain amino acids (BCAAs) L-leucine, L-isoleucine, and L-valine. BCATs are the key enzymes of BCAA metabolism in all organisms. The catalysis proceeds through the ping-pong mechanism with the assistance of the cofactor pyridoxal 5'-phosphate (PLP).
