- Thiosulfate-dithiol sulfurtransferase
In
enzymology , a thiosulfate-dithiol sulfurtransferase (EC number|2.8.1.5) is anenzyme that catalyzes thechemical reaction :thiosulfate + dithioerythritol sulfite + 4,5-cis-dihydroxy-1,2-dithiacyclohexane (i.e. oxidized dithioerythritol) + sulfide
Thus, the two substrates of this enzyme are
thiosulfate anddithioerythritol , whereas its 3 products aresulfite ,4,5-cis-dihydroxy-1,2-dithiacyclohexane , andsulfide .This enzyme belongs to the family of
transferase s, specifically the sulfurtransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is thiosulfate:dithioerythritol sulfurtransferase. Other names in common use include thiosulfate reductase, and TSR. This enzyme participates insulfur metabolism .References
