本酶催化的反应为Zeaxanthin + 4 Reduced Ferredoxin [Iron-Sulfur] Cluster + 4 H+ + 2 O2 = Violaxanthin + 4 Oxidized Ferredoxin [Iron-Sulfur] Cluster + 2 H2O (Overall Reaction);;(1a) Zeaxanthin + 2 Reduced Ferredoxin [Iron-Sulfur] Cluster + 2 H+ + O2 = Antheraxanthin + 2 Oxidized Ferredoxin [Iron-Sulfur] Cluster + H2O;;(1b) Antheraxanthin + 2 Reduced Ferredoxin [Iron-Sulfur] Cluster + 2 H+ + O2 = Violaxanthin + 2 Oxidized Ferredoxin [Iron-Sulfur] Cluster + H2O,系统名称为Zeaxanthin,reduced Ferredoxin:oxygen Oxidoreductase,一种在弱光条件下有活性的黄素蛋白(FAD)。该酶与 EC 1.23.5.1,紫黄素脱环氧化酶共同构成叶黄素(或紫黄素)循环,该循环参与保护植物免受强光伤害。在某些高等植物物种中它还使叶黄素环氧化。
