General annotation (Comments)

Function

Catalyzes the formation of the isocyclic ring in chlorophyll biosynthesis. Mediates the cyclase reaction, which results in the formation of divinylprotochlorophyllide (Pchlide) characteristic of all chlorophylls from magnesium-protoporphyrin IX 13-monomethyl ester (MgPMME) By similarity. HAMAP MF_01840

Catalytic activity

131-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O2 = 131-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADP+ + 2 H2O. HAMAP MF_01840

131-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O2 = divinylprotochlorophyllide + NADP+ + 2 H2O. HAMAP MF_01840

Magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O2 = 131-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADP+ + H2O. HAMAP MF_01840

Cofactor

Iron By similarity. HAMAP MF_01840

Pathway

Porphyrin biosynthesis; chlorophyll biosynthesis (light-independent). HAMAP MF_01840

Sequence similarities

Belongs to the AcsF family. HAMAP MF_01840
