branched-chain-amino-acid transaminase
branched-chain-ami·no-ac·id trans·am·i·nase (brancht-chān-ə-meґno-asґid trans-amґĭ-nās) [EC 2.6.1.42] an enzyme of the transferase class that catalyzes the removal of the α-amino group of leucine, isoleucine, or valine to form the corresponding keto acid, transferring the amino group to α-ketoglutarate or a similar acceptor. The reaction is the first step in the catabolism of branched-chain amino acids. In some persons the enzyme for leucine and isoleucine is distinguishable from the one for valine. Called also branched-chain-amino-acid aminotransferase.
