Synchrotron SAXS data from solutions of Rab family protein CtRoc-COR (nucleotide free) in 20 mM HEPES 150 mM NaCl 5 mM MgCl2 5% Glycerol 1 mM DTT, pH 7.5 were collected on the SWING camera on the storage ring SOLEIL (Saint-Aubin, France) using a CCD AVIEX detector at a wavelength of λ = 0.103 nm (I(s) vs s, where s = 4πsin θ/λ and 2θ is the scattering angle). Inline SEC-SAXS was employed at 25°C (50 µl injection volume of an 8 mg/ml protein solution on a Bio SEC-3 HPLC column (Agilent, 3 µm 300 Å)). 31 successive 0.750 second frames were collected through the elution peak. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted and the different curves were scaled and averaged to produce the final SAXS data displayed in this entry.
