Chain A,D (MCRA_METTM | P11558)

molecular function
	GO:0050524	coenzyme-B sulfoethylthiotransferase activity	Catalysis of the reaction: coenzyme B + methyl-coenzyme M = coenzyme M-coenzyme B heterodisulfide + methane. Methyl-CoM is also known as 2-(methylthio)ethanesulfonate, coenzyme B as N-(7-mercaptoheptanoyl)threonine 3-O-phosphate, and coenzyme M-coenzyme B heterodisulfide as CoM-S-S-CoB.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
	GO:0015948	methanogenesis	The chemical reactions and pathways resulting in the formation of methane, a colorless, odorless, flammable gas with the formula CH4. It is the simplest of the alkanes.
