	2.6.1.79
Description	Glutamate--prephenate aminotransferase.
Alternative names	prephenate transaminase (ambiguous); PAT (ambiguous); L-glutamate:prephenate aminotransferase; L-arogenate:2-oxoglutarate aminotransferase
Catalyzed reaction	L-arogenate + 2-oxoglutarate = prephenate + L-glutamate
Cofactor	Pyridoxal-phosphate.
Comments	A pyridoxal-phosphate protein. Aspartate can also act as the amino donor, but more slowly (cf. EC 2.6.1.78, aspartate—prephenate aminotransferase). The enzyme from higher plants shows a marked preference for prephenate as substrate compared to pyruvate, phenylpyruvate or 4-hydroxyphenylpyruvate.
