Superoxide reductase is anenzyme thatcatalyzes the conversion of highly reactive and toxicsuperoxide (O2−) into less toxichydrogen peroxide (H2O2):
Hydrogen peroxide in turn is reduced to water byrubrerythrin. The 3substrates of this enzyme arereduced rubredoxin,superoxide, andH+, whereas its twoproducts arerubredoxin andH2O2.
This enzyme belongs to the family ofoxidoreductases, specifically those acting on superoxide as acceptor (only sub-subclass identified to date). Thesystematic name of this enzyme class isrubredoxin:superoxide oxidoreductase. Other names in common use includeneelaredoxin, anddesulfoferrodoxin.
As of late 2007[update], 9structures have been solved for this class of enzymes, withPDB accession codes1VZG,1VZH,1VZI,1Y07,2AMU,2HVB,2JI1,2JI2, and2JI3.
