In enzymology, a dimethylpropiothetin dethiomethylase (EC 4.4.1.3) is an enzyme that catalyzes the chemical reaction

S,S-dimethyl-beta-propiothetin \rightleftharpoons dimethyl sulfide + acrylate

Hence, this enzyme has one substrate, S,S-dimethyl-beta-propiothetin, and two products, dimethyl sulfide and acrylate.

This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is S,S-dimethyl-beta-propiothetin dimethyl-sulfide-lyase (acrylate-forming). Other names in common use include desulfhydrase, and S,S-dimethyl-beta-propiothetin dimethyl-sulfide-lyase.
