This pathway involves the transamination of prephenate to form pretyrosine . 这一途径包括预苯酸的转氨基作用,形成预酪氨酸。
Both prephenate dehydrogenase and prephenate dehydratase have been isolated from plants . 预苯酸脱氢酶和预苯酸脱水酶都已从植物中分离出来。
Chorismate acid is branch point in aromatic amino acids biosynthesis , related to phenylalanine , bifunctional enzymes chorismate mutase / prephenate dehydratase ( encoded by phea ) is rate - limiting enzyme 分支酸是芳香族氨基酸合成途径的分支点,与苯丙氨酸合成有关,双功能酶分支酸变位酶-预苯酸脱水酶( phea基因编码)是关键酶。
