IntEnz Enzyme Nomenclature


Accepted name:
leucine transaminase
Other names:
L-leucine aminotransferase
leucine 2-oxoglutarate transaminase
leucine aminotransferase
leucine—α-ketoglutarate transaminase
Systematic name:
L-leucine:2-oxoglutarate aminotransferase




A pyridoxal-phosphate protein. This enzyme differs from EC, 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.
