DE RecName: Full=Aerobic magnesium-protoporphyrin IX monomethyl ester [oxidative] cyclase; DE Short=Aerobic Mg-protoporphyrin IX monomethyl ester oxidative cyclase; DE EC=1.14.13.81; GN Name=acsF; OrderedLocusNames=BRADO1649; OS Bradyrhizobium sp. (strain ORS278). OC Bacteria; Proteobacteria; Alphaproteobacteria; Rhizobiales; OC Bradyrhizobiaceae; Bradyrhizobium. OX NCBI_TaxID=114615; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RX PubMed=17540897; DOI=10.1126/science.1139548; RA Giraud E., Moulin L., Vallenet D., Barbe V., Cytryn E., Avarre J.-C., RA Jaubert M., Simon D., Cartieaux F., Prin Y., Bena G., Hannibal L., RA Fardoux J., Kojadinovic M., Vuillet L., Lajus A., Cruveiller S., RA Rouy Z., Mangenot S., Segurens B., Dossat C., Franck W.L., RA Chang W.-S., Saunders E., Bruce D., Richardson P., Normand P., RA Dreyfus B., Pignol D., Stacey G., Emerich D., Vermeglio A., RA Medigue C., Sadowsky M.; RT "Legumes symbioses: absence of nod genes in photosynthetic RT bradyrhizobia."; RL Science 316:1307-1312(2007). CC -!- FUNCTION: Catalyzes the formation of the isocyclic ring in CC chlorophyll biosynthesis. Mediates the cyclase reaction, which CC results in the formation of divinylprotochlorophyllide (Pchlide) CC characteristic of all chlorophylls from magnesium-protoporphyrin CC IX 13-monomethyl ester (MgPMME) (By similarity). CC -!- CATALYTIC ACTIVITY: Magnesium-protoporphyrin IX 13-monomethyl CC ester + NADPH + O(2) = 13(1)-hydroxy-magnesium-protoporphyrin IX CC 13-monomethyl ester + NADP(+) + H(2)O. CC -!- CATALYTIC ACTIVITY: 13(1)-hydroxy-magnesium-protoporphyrin IX 13- CC monomethyl ester + NADPH + O(2) = 13(1)-oxo-magnesium- CC protoporphyrin IX 13-monomethyl ester + NADP(+) + 2 H(2)O. CC -!- CATALYTIC ACTIVITY: 13(1)-oxo-magnesium-protoporphyrin IX 13- CC monomethyl ester + NADPH + O(2) = divinylprotochlorophyllide + CC NADP(+) + 2 H(2)O. CC -!- COFACTOR: Iron (By similarity). CC -!- PATHWAY: Porphyrin biosynthesis; bacteriochlorophyll biosynthesis CC (light-independent). CC -!- SIMILARITY: Belongs to the acsF family.
