产品内容
本酶催化的反应为L-Phenylalanine + 2 [Reduced NADPH---Hemoprotein Reductase] + 2 O2 = (E)-Phenylacetaldoxime + 2 [Oxidized NADPH---Hemoprotein Reductase] + CO2 + 3 H2O (Overall Reaction);;(1a) L-Phenylalanine + [Reduced NADPH---Hemoprotein Reductase] + O2 = N-Hydroxy-L-Phenylalanine + [Oxidized NADPH---Hemoprotein Reductase] + H2O;;(1b) N-Hydroxy-L-Phenylalanine + [Reduced NADPH---Hemoprotein Reductase] + O2 = N,N-Dihydroxy-L-Phenylalanine + [Oxidized NADPH---Hemoprotein Reductase] + H2O;;(1c) N,N-Dihydroxy-L-Phenylalanine = (E)-Phenylacetaldoxime + CO2 + H2O，系统名称为L-Phenylalanine,[reduced NADPH---Hemoprotein Reductase]:oxygen Oxidoreductase (N-Hydroxylating)，这种细胞色素 P-450（血红素-硫醇盐）酶存在于植物中，催化 L-苯丙氨酸的两次连续 N-羟基化，是苄基硫代葡萄糖苷以及生氰糖苷 (R)-野黑樱苷（prunasin）和 (R)-扁桃腈葡糖苷（amygdalin）生物合成的关键步骤。两次羟基化的产物 N,N-二羟基-L-苯丙氨酸不稳定，经脱水随后脱羧生成肟。目前尚不清楚脱羧是自发进行还是由酶催化。
