本酶催化的反应为2-(L-Cystein-S-Yl)-2-(1H-Indol-3-Yl)acetonitrile + 2 [Reduced NADPH---Hemoprotein Reductase] + 2 O2 = Camalexin + Hydrogen Cyanide + CO2 + 2 [Oxidized NADPH---Hemoprotein Reductase] + 4 H2O (Overall Reaction);;(1a) 2-(L-Cystein-S-Yl)-2-(1H-Indol-3-Yl)acetonitrile + [Reduced NADPH---Hemoprotein Reductase] + O2 = (R)-Dihydrocamalexate + Hydrogen Cyanide + [Oxidized NADPH---Hemoprotein Reductase] + 2 H2O;;(1b) (R)-Dihydrocamalexate + [Reduced NADPH---Hemoprotein Reductase] + O2 = Camalexin + CO2 + [Oxidized NADPH---Hemoprotein Reductase] + 2 H2O，系统名称为2-(Cystein-S-Yl)-2-(1H-Indol-3-Yl)-Acetonitrile, [Reduced NADPH---Hemoprotein Reductase]:oxygen Oxidoreductase (Camalexin-Forming)，这种细胞色素 P-450（血红素-硫醇盐）酶源自植物拟南芥（Arabidopsis thaliana），催化该植物主要植保素——亚麻荠素（camalexin）生物合成的最后两步。该酶催化两次连续的氧化事件：第一次氧化中该酶引入一个 C-N 双键并释放氰化氢，第二次氧化中催化脱羧。
