Thiosulfate—thiol sulfurtransferase

This enzyme belongs to the family of transferases, specifically the sulfurtransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is thiosulfate:thiol sulfurtransferase. Other names in common use include glutathione-dependent thiosulfate reductase, sulfane reductase, and sulfane sulfurtransferase. This enzyme participates in glutathione metabolism.
