Protein Domain : IPR011772

Type:  Family Name:  Magnesium-protoporphyrin IX monomethyl ester anaerobic oxidative cyclase
Description:  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. Short Name:  BchE
