– Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S cluster, can transfer this cluster to apoproteins, and thereby intervenes in the maturation of Fe/S proteins. Could also act as a scaffold/chaperone for damaged Fe/S proteins. NfuA Protein, Vibrio vulnificus, Recombinant is expressed in E. coli expression system. The predicted molecular weight is 21.0 kDa and the accession number is Q8DDU2.
