The enzyme L-3-cyanoalanine synthase (EC 4.4.1.9) catalyzes the chemical reaction

L-cysteine + hydrogen cyanide [math]\displaystyle{ \rightleftharpoons }[/math] L-3-cyanoalanine + hydrogen sulfide

This enzyme belongs to the family of lyases, specifically the class of carbon-sulfur lyases. The systematic name of this enzyme class is L-cysteine hydrogen-sulfide-lyase (adding hydrogen cyanide L-3-cyanoalanine-forming). Other names in common use include β-cyanoalanine synthase, β-cyanoalanine synthetase, β-cyano-L-alanine synthase, and L-cysteine hydrogen-sulfide-lyase (adding HCN). This enzyme participates in cyanoamino acid metabolism.
