COMMENT - Coenzyme B is one of the many unusual cofactors present in methanogens and required for methane formation.  Coenzyme B, similar to Coenzyme F420, acts an an electron carrier in the metabolism of methanogens.  All catabolic processes in methanogenesis lead to the formation of a mixed disulfide bond between coenzyme M and coenzyme B that functions as an electron acceptor of certain anaerobic respiratory chains  |CITS: [12102556]| .
