Mutation in Fe-S scaffold Isu bypasses frataxin deletion

Frataxin is a conserved mitochondrial protein deficient in patients with Friedreich's ataxia. Frataxin has been implicated in control of iron homoeostasis and Fe-S cluster assembly. In yeast or human mitochondria, frataxin interacts with components of the Fe-S cluster synthesis machinery, including the cysteine desulfurase Nfs1, accessory protein Isd11 and scaffold protein Isu.
