Name

S-Methyl-L-methionine

Species

Strain

Baker's yeast

Description

S-Methylmethionine is a derivative of methionine. 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. [Wikipedia]
