CC -!- FUNCTION: Catalyzes the formation of the isocyclic ring in chlorophyll
CC biosynthesis under oxygen- and copper-deficient conditions. Mediates
CC the cyclase reaction, which results in the formation of
CC divinylprotochlorophyllide (Pchlide) characteristic of all chlorophylls
CC from magnesium-protoporphyrin IX 13-monomethyl ester (MgPMME).
CC {ECO:0000269|PubMed:10811605, ECO:0000269|PubMed:12485992}.
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 -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875; Evidence={ECO:0000250};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; chlorophyll
CC biosynthesis.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000269|PubMed:11910013, ECO:0000269|PubMed:12485992}.
CC -!- INDUCTION: Induced in absence of copper and oxygen. Regulated by CRR1
CC protein, which activates its transcription in absence of copper.
CC {ECO:0000269|PubMed:10811605, ECO:0000269|PubMed:11842150,
CC ECO:0000269|PubMed:11910013}.
CC -!- SIMILARITY: Belongs to the AcsF family. {ECO:0000305}.
