In enzymology a hydrogensulfite reductase (EC 1.8.99.3) is an enzyme that catalyzes the chemical reactiontrithionate + acceptor + 2 H2O + OH- 3 bisulfite + reduced acceptorThe 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.
