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].	Domain
