Identification of iron(III) peroxo species in the active site of the superoxide reductase SOR from Desulfoarculus baarsii [PDF]
Journal of the American Chemical Society, American Chemical
Society, 2002, pp.4966-7, 2015 The active site of superoxide reductase SOR consists of an Fe2+ center in an unusual [His4 Cys1] square-pyramidal geometry. It specifically reduces superoxide to produce H2O2. Here, we have reacted the SOR from Desulfoarculus baarsii directly with H2O2.

Journal of Biological Chemistry, 1999 Plant-type ferredoxin (Fd), a [2Fe-2S] iron-sulfur protein, functions as an one-electron donor to Fd-NADP+ reductase (FNR) or sulfite reductase (SiR), interacting electrostatically with them. In order to understand the protein-protein interaction between

The effects of the preincubation with vitamin B2-acid on ferredoxin-NADP+ reductase.
Journal of Nutritional Science and Vitaminology, 1990 The effects of vitamin B2-acid on both cytochrome c reductase and diaphorase activities of ferredoxin-NADP+ reductase [EC 1.18.1.2] were investigated with enzyme kinetics. Vitamin B2-acid was shown to serve as an electron carrier for the two activities, as well as riboflavin or flavin mononucleotide (FMN). The two activities, however, were irreversibly

Superoxide reductase from Desulfoarculus baarsii: reaction mechanism and role of glutamate 47 and lysine 48 in catalysis [PDF]
Biochemistry, American Chemical Society, 2001, pp.5032-40, 2015 Superoxide reductase (SOR) is a small metalloenzyme that catalyzes reduction of O(2)(*)(-) to H(2)O(2) and thus provides an antioxidant mechanism against superoxide radicals. Its active site contains an unusual mononuclear ferrous center, which is very efficient during electron transfer to O(2)(*)(-) [Lombard, M., Fontecave, M., Touati, D., and Nivi ...

Fe(3+)-eta(2)-peroxo species in superoxide reductase from Treponema pallidum. Comparison with Desulfoarculus baarsii [PDF]
Biophysical Chemistry, Elsevier, 2006, pp.38-48, 2015 Superoxide reductases (SORs) are superoxide (O2-)-detoxifying enzymes that catalyse the reduction of O2- into hydrogen peroxide. Three different classes of SOR have been reported on the basis of the presence or not of an additional N-terminal domain. They all share a similar active site, with an unusual non-heme Fe atom coordinated by four equatorial ...
