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.
