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).
Catalytic activity RHEA:33235: 2 H(+) + Mg-protoporphyrin IX 13-monomethyl ester + 3 NADPH + 3 O2 = 3,8-divinyl protochlorophyllide a + 5 H2O + 3 NADP(+)
EC 1.14.13.81
Cofactor Fe cation
case <OC:Bacteria> and not <OC:Cyanobacteria>
Pathway Porphyrin-containing compound metabolism; bacteriochlorophyll biosynthesis (light-independent).
end case
case <OC:Cyanobacteria> or <OG:Chloroplast>
Pathway Porphyrin-containing compound metabolism; chlorophyll biosynthesis (light-independent).
end case
case <OG:Chloroplast>
Subcellular location Plastid, chloroplast.
end case
Similarity Belongs to the AcsF family.
