Experimental SAXS data of PPARγ/RXRα LBDs complexes. (a) Scattering profiles of PPARγ/RXRα LBDs (red) and TIF2 RID/PPARγ/RXRα LBDs (pink). (b) Distance distribution functions computed from the X-ray scattering patterns using the program GNOM. Same color code as in (a). (c) Kratky representations for TIF2 RID (blue) and TIF2 RID/PPARγ/RXRα LBDs (green).
