CC   -!- FUNCTION: Catalyzes the formation of the isocyclic ring in chlorophyll
CC       biosynthesis. Mediates the cyclase reaction, which results in the
CC       formation of divinylprotochlorophyllide (Pchlide) characteristic of all
CC       chlorophylls from magnesium-protoporphyrin IX 13-monomethyl ester
CC       (MgPMME). {ECO:0000255|HAMAP-Rule:MF_01840}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H(+) + Mg-protoporphyrin IX 13-monomethyl ester + 3 NADPH +
CC         3 O2 = 3,8-divinyl protochlorophyllide a + 5 H2O + 3 NADP(+);
CC         Xref=Rhea:RHEA:33235, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:15379, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349,
CC         ChEBI:CHEBI:58632, ChEBI:CHEBI:60491; EC=1.14.13.81;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01840};
CC   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01840};
CC   -!- PATHWAY: Porphyrin-containing compound metabolism; bacteriochlorophyll
CC       biosynthesis (light-independent). {ECO:0000255|HAMAP-Rule:MF_01840}.
CC   -!- SIMILARITY: Belongs to the AcsF family. {ECO:0000255|HAMAP-
CC       Rule:MF_01840}.
