Accepted name: branched-chain-amino-acid transaminase
Reaction: L-leucine + 2-oxoglutarate = 4-methyl-2-oxopentanoate + L-glutamate
Other name(s): transaminase B; branched-chain amino acid aminotransferase; branched-chain amino acid-glutamate transaminase; branched-chain aminotransferase; L-branched chain amino acid aminotransferase; glutamate-branched-chain amino acid transaminase
Systematic name: branched-chain-amino-acid:2-oxoglutarate aminotransferase
Comments: Also acts on L-isoleucine and L-valine, and thereby differs from EC, leucine transaminase, which does not. It also differs from EC, valine—pyruvate transaminase.
