This short domain is found at the N-terminal end of class III superoxide reductase from Treponema pallidum (SOR, [swissprot:O83795]), a small protein that catalyse the one -electron reduction of superoxide to hydrogen peroxide, having rubredoxin as their putative electron donor. It is organised into two distinct domains: an N-terminal (this entry) that shows four beta-strands and a C-terminal that harbours the catalytic site and displays an immunoglobulin-like fold [1].
Desulfoferrodoxins contains two types of iron: an Fe-S4 site very similar to that found in desulforedoxin from Desulfovibrio gigas and an octahedral coordinated high-spin ferrous site most probably with nitrogen/oxygen-containing ligands. Due to this ...
Desulfoferrodoxins contains two types of iron: an Fe-S4 site very similar to that found in desulforedoxin from Desulfovibrio gigas and an octahedral coordinated high-spin ferrous site most probably with nitrogen/oxygen-containing ligands. Due to this rather unusual combination of active centres, this novel protein is named desulfoferrodoxin [1].
