Able to cleave dimethylsulfonioproprionate (DMSP), releasing dimethyl sulfide (DMS). DMS is the principal form by which sulfur is transported from oceans to the atmosphere. S,S-dimethyl-beta-propiothetin = acrylate + dimethyl sulfide + H(+) Cells are unable to produce dimethyl sulfide (DMS) from dimethylsulfonioproprionate (DMSP). Cells however grow normally on DMSP as sole carbon source.
