Dimethylsulfoniproprionate (DMSP) is a common metabolite produced by marine microorganisms and it acts as a significant carbon and sulfur source for marine bacteria. Degradation of DMSP occurs by either the cleavage pathway or the demethylation pathway <ref> Reisch, C.R., Moran, M.A., Whitman, W.B. (2008). Dimethylsulfoniopropionate-Dependent Demethylase (DmdA) from Pelagibacter ubique and Silicibacter pomeroyi. J. Bacteriol. 190: 8018-8024. </ref>. The demethylation pathway is characterized by the conversion of DMSP into methylmercaptopropionate (MMPA). Dimethylsulfoniopropionate-Dependendent Demethylase (DmdA) is the first enzyme in the demethylation pathway and facilitates this conversion by acting as a methyl transferase. | Dimethylsulfoniproprionate (DMSP) is a common metabolite produced by marine microorganisms and it acts as a significant carbon and sulfur source for marine bacteria.

In addition to requiring DMSP as a substrate, DmdA also requires (THF) as a cofactor. | ||
