Thiosulfate sulfurtransferase (also known as rhodanese) can facilitate the transfer of a sulfur atom from sulfur donors to nucleophilic sulfur acceptors, and it has been found in many major phyla (prokaryotic and eukaryotic). The role of thiosulfate sulfurtransferase might be the detoxification of cyanide in both bacteria and mammals, or it might also involve in formation of prosthetic groups in iron-sulfur proteins. In this pathway, thiosulfate and hydrogen cyanide have been catalyzed by thiosulfate sulfurtransferase to form thiocyanate and sulfite. Sulfite is used in later sulfur metabolism.
