S-Methylmethionine is a derivative of methionine with the chemical formula [(CH3)3S(CH2)2CHNH3CO2]+. This cation is an intermediate in many biosynthetic pathways owing to the sulfonium functional group. The natural derivative S-methylmethionine is biosynthesized from L-methionine which is first converted to S-adenosylmethionine. The subsequent conversion, involving replacement of the adenosyl group by a methyl group is catalyzed by the enzyme methionine S-methyltransferase. S-Methylmethionine is particularly abundant in plants, being more abundant than methionine.[2]
Biochemical function
The osmolyte dimethylsulfoniopropionate (DMSP), produced by marine algae, is biosynthesized from S-methylmethionine. Intermediates include dimethylsulfoniumpropylamine and dimethylsulfoniumpropionaldehyde.[3]
Beer flavor precursor in barley malt
S-Methylmethionine is found in barley and during the malting process, particularly the curing stage in kilning, heat causes it to break down to form dimethyl sulfide (DMS).[4]
