A pyridoxal-phosphate protein. This enzyme differs from EC 188.8.131.52, branched-chain-amino-acid transaminase, in that it does not act on L-valine or L-isoleucine, although it does act on L-methionine. The mitochondrial form from rat liver differs in physical characteristics from the cytoplasmic form.
