Comparison of results from SAXS experiments for several complexes involving IscS. (A) Cartoon representations of the IscX–IscS, IscU–IscS, Fdx–IscS,⁸ CyaY–IscS,¹⁵ and IscX–IscU–IscS complexes. (B) Experimentally determined radius of gyration for IscS and the complexes depicted in A. (C) Experimentally determined D_max for IscS and the complexes depicted in A. (D) Distance distribution functions determined from experimental SAXS data from IscS and the complexes depicted in A.
