Catalysis of the transfer of a methyl group to an acceptor molecule. Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate. Catalysis of the reaction: S-adenosyl-L-methionine + L-homocysteine = S-adenosyl-L-homocysteine + L-methionine. Catalysis of the transfer of a methyl group to the sulfur atom of an acceptor molecule.
