title: [The mechanism of action of S-methylmethionine].
abstract: S-methyl methionine was found to increase activity of S-adenosyl-L-homocysteine hydrolase, selectively methylating the released homocysteine. This decreased the inhibitory effect of S-adenosyl-L-homocysteine and stimulated methylation processes.
