Superfamily: BFD-like [2Fe-2S]-binding domain

The two Fe ions are each coordinated by two conserved cysteine residues. This domain occurs alone in small proteins such as bacterioferritin-associated ferredoxin (BFD, P13655). The function of BFD is not known, but it may be a general redox and/or regulatory component involved in the iron storage or mobilisation functions of bacterioferritin in bacteria PMID:8639572. This domain is also found in nitrate reductase proteins in association with the nitrite and sulphite reductase 4Fe-4S domain (PFAM:PF01077, INTERPRO:IPR006067), nitrite/sulphite reductase ferredoxin-like half domain (PFAM:PF03460, INTERPRO:IPR005117). It is also found in NifU nitrogen fixation proteins, in association with NifU-like N-terminal domain (PFAM:PF00070, INTERPRO:IPR002871) and C-terminal domain (PFAM:PF01106, INTERPRO:IPR001075).
