Detoxification of superoxide without production of H2O2: antioxidant activity of superoxide reductase complexed with ferrocyanide [PDF]

proceedings of the national Academy of Sciences of the United States of America, PNAS, 2006, pp.14750-5, 2015
The superoxide radical O(2)(-.) is a toxic by-product of oxygen metabolism. Two O(2)(-.) detoxifying enzymes have been described so far, superoxide dismutase and superoxide reductase (SOR), both forming H2O2 as a reaction product. Recently, the SOR active site, a ferrous iron in a [Fe(2+) (N-His)(4) (S-Cys)] pentacoordination, was shown to have the ...
