Small-angle X-ray scattering experiments for Cg-mtEXO. a Model of full-length (fl) Cg-mtEXO calculated using Bilbo. b Model of fl-Cg-mtEXO with superimposed three-dimensional reconstruction from SAXS data for fl-Cg-mtEXO (gray spheres). c Model of fl-Cg-mtEXO with superimposed three-dimensional reconstruction from SAXS data for Cg-Dss1-Suv3183-699 (gray spheres). d Comparison of the computed X-ray scattering curve for fl-Cg-mtEXO model shown in a (cyan) with the scattering data collected for fl-Cg-mtEXO (black circles). e The best model obtained from docking Cg-Suv3183-699 to Cg-Dss1 using FoxsDock28. Cg-Dss1 is shown in gray surface representation. The Suv3 subunit from the Cg-mtEXO crystal structure is shown as a red wire. The position of Cg-Suv3 in the best-scored model is shown as a blue wire. f Comparison of the computed scattering curve for the model from docking shown in e (orange) with the SAXS data for Cg-Dss1-Suv3183–699 (black circles)
