Hydrogensulfite reductase

In enzymology, a hydrogensulfite reductase (EC number|1.8.99.3) is an enzyme that catalyzes the chemical reaction

:trithionate + acceptor + 2 H₂O + OH- $ightleftharpoons$ 3 bisulfite + reduced acceptor

The 4 substrates of this enzyme are trithionate, acceptor, H₂O, and OH-, whereas its two products are bisulfite and reduced acceptor.

This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with other acceptors. The systematic name of this enzyme class is trithionate:acceptor oxidoreductase. Other names in common use include bisulfite reductase, dissimilatory sulfite reductase, desulfoviridin, desulforubidin, desulfofuscidin, dissimilatory-type sulfite reductase, and trithionate:(acceptor) oxidoreductase. It has 4 cofactors: iron, Sulfur, Siroheme, and Iron-sulfur.
