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 18.104.22.168 aspartate transaminase.
