PFAM accession number:PF00111
Interpro abstract (IPR001041):

Ferredoxins are small, acidic, electron transfer proteins that are ubiquitous in biological redox systems. They have either 4Fe-4S, 3Fe-4S, or 2Fe-2S cluster. Among them, ferredoxin with one 2Fe-2S cluster per molecule are present in plants, animals, and bacteria, and form a distinct Ferredoxin family [ (PUBMED:2065785) ]. They are proteins of around one hundred amino acids with four conserved cysteine residues to which the 2Fe-2S cluster is ligated. This conserved region is also found as a domain in various metabolic enzymes.

Several structures of the 2Fe-2S ferredoxin-type domain have been determined [ (PUBMED:8586613) ]. The domain is classified as a beta-grasp, which is characterised as having a beta-sheet comprised of four beta-strands and one alpha-helix flanking the sheet. The two Fe atoms are coordinated tetrahedrally by the two inorganic S atoms and four cysteinyl S atoms.

GO function:iron-sulfur cluster binding (GO:0051536), electron transfer activity (GO:0009055)
