Identification of iron(III) peroxo species in the active site of the superoxide reductase SOR from Desulfoarculus baarsii
Christelle Mathé, Tony A Mattioli, Olivier Horner +4
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…
Pulse radiolysis studies on superoxide reductase from Treponema pallidum
V Nivière, M. Lombard, M. Fontecave +1
Superoxide reductases (SORs) are small metalloenzymes, which catalyze reduction of O2*- to H2O2. The reaction of the enzyme from Treponema pallidum with superoxide was studied by p…
Superoxide reductase from Desulfoarculus baarsii: reaction mechanism and role of glutamate 47 and lysine 48 in catalysis
M. Lombard, C. Houée-Levin, D. Touati +2
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 a…
Reaction of the desulfoferrodoxin from Desulfoarculus baarsii with superoxide anion. Evidence for a superoxide reductase activity
M Lombard, M Fontecave, D Touati +1
Desulfoferrodoxin is a small protein found in sulfate-reducing bacteria that contains two independent mononuclear iron centers, one ferric and one ferrous. Expression of desulfofer…
Superoxide reductase from Desulfoarculus baarsii
Vincent Nivière, Murielle Lombard
Superoxide radical (O2.-) is the univalent reduction product of molecular oxygen and belongs to the group of the so-called toxic oxygen derivatives. For years the only enzymatic sy…
