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. |
| Catalytic activity | Magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O(2) = 13(1)-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADP(+) + H(2)O. 13(1)-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O(2) = 13(1)-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADP(+) + 2 H(2)O. 13(1)-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O(2) = divinylprotochlorophyllide + NADP(+) + 2 H(2)O. |
| Cofactor | Iron By similarity. |
| Pathway | Porphyrin biosynthesis; chlorophyll biosynthesis (light-independent). |
| Subcellular location | |
| Sequence similarities | Belongs to the acsF family. |
