| Short Name | Desulfoferrodoxin_Fe-bd_dom |
| description | Desulfoferrodoxins contains two types of iron: an Fe-S4 site very similar to that found in desulfoferrodoxin 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 []. The desulfoferrodoxin domain comprises essentially the full length of neelaredoxin ([]), a monomeric, blue, non-haem iron protein of D. gigas said to bind two iron atoms per monomer with identical spectral properties. Neelaredoxin was shown recently to have significant superoxide dismutase activity []. This domain is also found (in a form in which the distance between the motifs H[HWYF]IXW and CN[IL]HGXW is somewhat shorter) as the C-terminal domain of desulfoferrodoxin, which is said to bind a single ferrous iron atom.The N-terminal domain of desulfoferrodoxin is described by . |
