A yet to be identified enzyme with methylselenol methyltransferase (MeSeHMT) activity is involved in the methylation of methylselenol aka methaneselenol (MeSeH) into dimethyl selenide (Me2Se) in tandem with S-adenosylmethionine (AdoMet) transforming into S-adenosylhomocysteine (AdoHcy). This reaction is inferred from the event in rat (Ohta and Suzuki 2008, Hsieh and Ganther 1977).
