D-cysteine desulfhydrase

The enzyme  D -cysteine desulfhydrase (EC 4.4.1.15) catalyzes the chemical reaction


 * D -cysteine + H2O $$\rightleftharpoons$$ sulfide + NH3 + 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.
