FeS assembly ATPase SufC SufC is part of the SUF system, shown in E. coli to consist of six proteins and believed to act in Fe-S cluster formation during oxidative stress. SufC forms a complex with SufB and SufD. SufC belongs to the ATP-binding cassette transporter family (pfam00005) but is no longer thought to be part of a transporter. The complex is reported as cytosolic () or associated with the membrane (). The SUF system also includes a cysteine desulfurase (SufS, enhanced by SufE) and a probable iron-sulfur cluster assembly scaffold protein, SufA.
