In enzymology, a D-cysteine desulfhydrase (EC 4.4.1.15) is an enzyme that catalyzes the chemical reaction
- D-cysteine + H2O
sulfide + NH3 + pyruvate
Thus, the two substrates of this enzyme are D-cysteine and H2O, whereas its 3 products are sulfide, NH3, and pyruvate.
This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is D-cysteine sulfide-lyase (deaminating; pyruvate-forming). Other names in common use include D-cysteine lyase, and D-cysteine sulfide-lyase (deaminating). This enzyme participates in cysteine metabolism.
