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	Reaction=2 H(+) + Mg-protoporphyrin IX 13-monomethyl ester + 3 NADPH + 3 O2 = 3,8-divinyl protochlorophyllide a + 5 H2O + 3 NADP(+); Xref=Rhea:RHEA:33235, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, ChEBI:CHEBI:58632, ChEBI:CHEBI:60491; EC=1.14.13.81;
COFACTOR	Name=Fe cation; Xref=ChEBI:CHEBI:24875;
case <OC:Bacteria> and not <OC:Cyanobacteriota>
PATHWAY	Porphyrin-containing compound metabolism; bacteriochlorophyll biosynthesis (light-independent).
end case
case <OC:Cyanobacteriota> or <OG:Chloroplast>
PATHWAY	Porphyrin-containing compound metabolism; chlorophyll biosynthesis (light-independent).
end case
case <OG:Chloroplast>
SUBCELLULAR LOCATION	Plastid, chloroplast.
