Metabolite Identification
Common NameS-Methylmethionine
DescriptionS-Methylmethionine (SMM) belongs to the class of organic compounds known as methionines and derivatives. Methionines and derivatives are compounds containing methionine or a derivative thereof resulting from reaction of methionine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. S-Methylmethionine is a derivative of methionine. It 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. As a result, S-Methylmethionine is found, on average, in the highest concentration within a few different plant foods, such as teas (Camellia sinensis), red tea, and herbal tea and in a lower concentration in green tea, black tea. It is also found in garden tomatoes. S-Methylmethionine has also been detected, but not quantified in, several different foods, such as prunus (cherry, plum), barley, nuts, root vegetables, onion-family vegetables, and sapodillas (Manilkara zapota). This could make S-methylmethionine a potential biomarker for the consumption of these foods. S-Methylmethionine is naturally found in barley and is further created during the malting process to produce beer. SMM can be subsequently converted to dimethyl sulfide (DMS) during the malt kilning process, causing an undesirable flavor in beer. Lightly kilned malts such as pilsner or lager malts retain much of their SMM content while higher kilned malt such as pale ale malt has substantially more of the SMM converted to DMS in the malt. S- The biological roles of S-methylmethionine are not well understood. Speculated roles include methionine storage, use as a methyl donor, regulation of S-adenosylmethionine.
