This family of proteins is found in prokaryotes, including the nickel responsive protein SCO4226 from Streptomyces coelicolor (Swiss:Q9FCE4). SCO4226 adopts a dimeric configuration able to bind four nickel ions, with each monomer showing a typical ferredoxin-like fold with five beta-strands packing against two alpha-helices. It seems to play a role in cellular nickel homeostasis, detoxification, and/or nickel utilization in specialised cytoplasmic compartment [1].
