本酶催化的反应为Magnesium-Protoporphyrin IX 13-Monomethyl Ester + 3 NADPH + 3 H+ + 3 O2 = 3,8-Divinyl Protochlorophyllide A + 3 NADP+ + 5 H2O (Overall Reaction);;(1a) Magnesium-Protoporphyrin IX 13-Monomethyl Ester + NADPH + H+ + O2 = 131-Hydroxy-Magnesium-Protoporphyrin IX 13-Monomethyl Ester + NADP+ + H2O;;(1b) 131-Hydroxy-Magnesium-Protoporphyrin IX 13-Monomethyl Ester + NADPH + H+ + O2 = 131-Oxo-Magnesium-Protoporphyrin IX 13-Monomethyl Ester + NADP+ + 2 H2O;;(1c) 131-Oxo-Magnesium-Protoporphyrin IX 13-Monomethyl Ester + NADPH + H+ + O2 = 3,8-Divinyl Protochlorophyllide A + NADP+ + 2 H2O，系统名称为Magnesium-Protoporphyrin-IX 13-Monomethyl Ester,NADPH:oxygen Oxidoreductase (Hydroxylating)，需要铁(II)才能发挥活性。该酶参与需氧生物中叶绿素酸酯a的生物合成。在厌氧生物中，相同的转化由EC 1.21.98.3（厌氧镁-原卟啉IX单甲酯环化酶）完成。一些兼性光合细菌，如胶状红长命菌（Rubrivivax gelatinosus），同时拥有这两种酶。
