Dimethylpropiothetin dethiomethylase

The enzyme dimethylpropiothetin dethiomethylase (EC 4.4.1.3) catalyzes the chemical reaction


 * S,S-dimethyl-β-propiothetin $$\rightleftharpoons$$ dimethyl sulfide + acrylate

The enzyme breaks S,S-dimethyl-β-propiothetin into 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-β-propiothetin dimethyl-sulfide-lyase (acrylate-forming). Other names in common use include desulfhydrase, and S,S-dimethyl-beta-propiothetin dimethyl-sulfide-lyase.
