In enzymology, a thioether S-methyltransferase (EC 2.1.1.96) is an enzyme that catalyzes the chemical reaction.
Thus, the two substrates of this enzyme are S-adenosyl methionine and dimethyl sulfide, whereas its two products are S-adenosylhomocysteine and trimethylsulfonium.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:dimethyl-sulfide S-methyltransferase. Other names in common use include S-adenosyl-L-methionine:thioether S-methyltransferase, and thioether methyltransferase.
S-Methylmethionine (SMM) is a derivative of methionine with the chemical formula (CH3)2S+CH2CH2CH(NH3+)CO2−. This cation is a naturally-occurring intermediate in many biosynthetic pathways owing to the sulfonium functional group. It is biosynthesized from L-methionine and S-adenosylmethionine by the enzyme methionine S-methyltransferase. S-methylmethionine is particularly abundant in plants, being more abundant than methionine.
