– 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, E. coli, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 25.1 kDa and the accession number is B1X760.
