Function
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).
Catalytic activity
- Mg-protoporphyrin IX 13-monomethyl ester + 3 NADPH + 3 O2 + 2 H+ = 3,8-divinyl protochlorophyllide a + 3 NADP+ + 5 H2O
Cofactor
Pathway
Porphyrin-containing compound metabolism; chlorophyll biosynthesis (light-independent).
