S-Methylcysteine is the amino acid with the nominal formula CH3SCH2CH(NH2)CO2H. It is the S-methylated derivative of cysteine. This amino acid occurs widely in plants, including many edible vegetables.




Natural occurrence


S-Methylcysteine is not genetically coded, but it arises by post-translational methylation of cysteine. One pathway involves methyl transfer from alkylated DNA by zinc-cysteinate-containing repair enzymes.
S-Methylcysteine sulfoxide is an oxidized derivative of S-methylcysteine that is found in [onion]]s.




Other chemical properties


Beyond its biological context, S-methylcysteine has been examined as a chelating agent.
