O is a cofactor of hydrogenases that is used to oxidize hydrogen and generate a proton motive force for methanogens. O is used in a select group of methanogens to transfer electrons in the membrane and generate protein motive force. O is the prosthetic group of the enzyme (methyl coenzyme M reductase) that catalyzes the terminal step of methanogenesis.
