CC   -!- FUNCTION: Methyltransferase involved in methanogenesis from methylated-
CC       thiols. Catalyzes two successive steps: mediates the transfer of a
CC       methyl group from the substrate to the cobalt cofactor of a methylated-
CC       thiol-specific corrinoid protein (MtsB), and the subsequent transfer of
CC       the methyl group from the corrinoid protein to coenzyme M (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=coenzyme M + methanethiol = H(+) + hydrogen sulfide + methyl-
CC         coenzyme M; Xref=Rhea:RHEA:32667, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:16007, ChEBI:CHEBI:29919, ChEBI:CHEBI:58286,
CC         ChEBI:CHEBI:58319; EC=2.1.1.251;
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the uroporphyrinogen decarboxylase family.
CC       {ECO:0000305}.
