Glutamate—prephenate aminotransferase : ウィキペディア英語版 | Glutamate—prephenate aminotransferase
In enzymology, glutamate-prephenate aminotransferase (, also known as prephenate transaminase, PAT, and L-glutamate:prephenate aminotransferase) is an enzyme that catalyzes the chemical reaction :L-arogenate + 2-oxoglutarate prephenate + L-glutamate Thus, the two substrates of this enzyme are L-arogenate and 2-oxoglutarate, whereas its two products are prephenate and L-glutamate. However, in most plant species utilizing this enzyme, the left side of the reaction is strongly favored. Therefore, glutamate is used as the amino donor to convert prephenate into arogenate. == Nomenclature ==
This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-arogenate:2-oxoglutarate aminotransferase. Other names in common use include prephenate transaminase (ambiguous), PAT (ambiguous), and L-glutamate:prephenate aminotransferase. It operates in the phenylalanine and tyrosine biosynthesis pathway.
