Each subunit contains a high-spin iron atom tetrahedrally bound to four cysteinyl sulphur atoms This family has a similar fold to the rubredoxin metal binding domain [1]. It is also found as the N-terminal domain of desulfoferrodoxin, see (Pfam:PF01880).

Due to this rather unusual combination of active centres, this novel protein is named desulfoferrodoxin [1].
