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 + O₂ = 13¹-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADP⁺ + H₂O.
CATALYTIC ACTIVITY: 13¹-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O₂ = 13¹-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADP⁺ + 2 H₂O.
CATALYTIC ACTIVITY: 13¹-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + O₂ = divinylprotochlorophyllide + NADP⁺ + 2 H₂O.
COFACTOR: Iron (By similarity).
PATHWAY: Porphyrin metabolism; chlorophyll biosynthesis (light-independent).
SUBCELLULAR LOCATION: Plastid, chloroplast.
SIMILARITY: Belongs to the acsF family.
