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.
