It forms a single structural domain with three functional regions (that bind FAD, the 4Fe4S cluster, and UQ) which are closely packed and share structural elements [1]. This domain includes the residues involved in UQ binding [1]. This domain is also found in FixC proteins from bacteria, which share similarities with ETF-QO [2].
