IUBMB Enzyme Nomenclature


Accepted name: aromatic-amino-acid transaminase

Reaction: An aromatic amino acid + 2-oxoglutarate = an aromatic oxo acid + L-glutamate

Other name(s): aromatic amino acid aminotransferase; aromatic aminotransferase; ArAT

Systematic name: aromatic-amino-acid:2-oxoglutarate aminotransferase

Comments: A pyridoxal-phosphate protein. L-Methionine can also act as donor, but more slowly; oxaloacetate can act as acceptor. Controlled proteolysis converts the enzyme into EC aspartate transaminase.
