In enzymology, a 3-mercaptopyruvate sulfurtransferase (EC 2.8.1.2) is an enzyme that catalyzes the chemical reaction

3-mercaptopyruvate + cyanide pyruvate + thiocyanate
3-mercaptopyruvate + thiol pyruvate + hydrogen sulfide

This enzyme belongs to the family of transferases, specifically the sulfurtransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3-mercaptopyruvate:cyanide sulfurtransferase. This enzyme is also called beta-mercaptopyruvate sulfurtransferase. This enzyme participates in cysteine metabolism.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1OKG and 1URH.
