== Function ==
[https://www.uniprot.org/uniprot/FER1_AZOVI FER1_AZOVI] Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. This ferredoxin could play a role in regulating gene expression by interacting directly with DNA.

== Publication Abstract from PubMed ==
Azotobacter vinelandii ferredoxin I is a small protein that contains one [4Fe-4S] cluster and one [3Fe-4S] cluster. Recently the x-ray crystal structure has been redetermined and the fdxA gene, which encodes the protein, has been cloned and sequenced. Here we report the site-directed mutation of Cys-20, which is a ligand of the [4Fe-4S] cluster in the native protein, to alanine and the characterization of the protein product by x-ray crystallographic and spectroscopic methods. The data show that the mutant protein again contains one [4Fe-4S] cluster and one [3Fe-4S] cluster. The new [4Fe-4S] cluster obtains its fourth ligand from Cys-24, a free cysteine in the native structure. The formation of this [4Fe-4S] cluster drives rearrangement of the protein structure.
