In &lt;taxon tax_id="354"&gt;Azotobacter vinelandii&lt;/taxon&gt;, it is a homodimer; each subunit contains one 2Fe-2S cluster [&lt;cite idref="PUB00016779"/&gt;], which is proposed to have a redox function involving the release of Fe for the biosynthesis of the Fe-S cluster at the labile rubredoxin-like site [&lt;cite idref="PUB00016841"/&gt;].&lt;/p&gt;</ns1:prib124u1i>
