A set of methyltransferases (MetTrans(1)) consisting of the proteins histamine-N-methyltransferase (HNMT), glycine-N-methyltransferase (GNMT), and nicotinamide-N-methyltransferase (NNMT) remove a methyl group from adenosylselenomethionine (AdoSeMet) to leave adenosylselenohomocysteine (AdeSeHCys). This reaction is inferred from the event in rat involving the set of methyltransferases (MetTrans(2)) consisting of the proteins histamine-N-methyltransferase (Hnmt), glycine-N-methyltransferase (Gnmt), and nicotinamide-N-methyltransferase (Nnmt) (Kajander et al. 1991).
