>TIGR02026 BchE magnesium-protoporphyrin IX monomethyl ester anaerobic oxidative cyclase; InterPro: IPR011772 This entry respresents the cobalamin-dependent oxidative cyclase responsible for forming the distinctive E-ring of the chlorin ring system under anaerobic conditions . This step is essential in the biosynthesis of both bacteriochlorophyll and chlorophyll under anaerobic conditions (a separate enzyme, AcsF, acts under aerobic conditions). This entry identifies two clades of sequences, one from photosynthetic, non-cyanobacterial bacteria and another including Synechocystis and several non-photosynthetic bacteria. The function of the Synechocystis gene is supported by gene clustering with other photosynthetic genes, so the purpose of the gene in the non-photosynthetic bacteria is uncertain. Note that homologues of this gene are not found in plants which rely solely on the aerobic cyclase.; GO: 0016709 oxidoreductase activity acting on paired donors with incorporation or reduction of molecular oxygen NADH or NADPH as one donor and incorporation of one atom of oxygen, 0050661 NADP binding, 0015995 chlorophyll biosynthetic process.
