| - | '''SAM-dependent methyltransferase''' (SDM) utilizes the methyl donor S-adenosyl-L-methionine (SAM) as a cofactor to methylate proteins, small molecules, lipids and nucleic acids. SAM forms S-adenosyl-L-homocysteine (SAH) upon demethylation. About 120 members of the SDM family have been identified. They differ in their substrate specificity and the atom targeted for methylation (N, O, C, S)<ref>PMID:23180741</ref>. | + | '''SAM-dependent methyltransferase''' or '''S-adenosylmethionine-dependent methyltransferase''' (SDM) utilizes the methyl donor S-adenosyl-L-methionine (SAM) as a cofactor to methylate proteins, small molecules, lipids and nucleic acids.
