IUBMB Enzyme Nomenclature


Accepted name: aspartate—prephenate aminotransferase

Reaction: L-arogenate + oxaloacetate = prephenate + L-aspartate

Other name(s): prephenate transaminase (ambiguous); PAT (ambiguous); prephenate aspartate aminotransferase; L-aspartate:prephenate aminotransferase

Systematic name: L-arogenate:oxaloacetate aminotransferase

Comments: A pyridoxal-phosphate protein. Glutamate can also act as the amino donor, but more slowly (cf. EC, glutamate—prephenate aminotransferase).
