Electron transfer flavoprotein FAD-binding domain; This domain found at the C-terminus of electron transfer flavoprotein alpha chain and binds to FAD. The fold consists of a five-stranded parallel beta sheet as the core of the domain, flanked by alternating helices. A small part of this domain is donated by the beta chain.
