Superoxide reductase

In enzymology, a superoxide reductase is an enzyme that catalyzes the chemical reaction


 * reduced rubredoxin + superoxide + 2 H+ $$\rightleftharpoons$$ rubredoxin + H2O2

The 3 substrates of this enzyme are reduced rubredoxin, superoxide, and H+, whereas its two products are rubredoxin and H2O2.

This enzyme belongs to the family of oxidoreductases, specifically those acting on superoxide as accepto acting on superoxide as acceptor (only sub-subclass identified t date). The systematic name of this enzyme class is rubredoxin:superoxide oxidoreductase. Other names in common use include neelaredoxin, and desulfoferrodoxin.
