Synchrotron SAXS data from solutions of Full length GtBP3 in 25 mM Tris/HCl 250 mM NaCl, pH 8 were collected on the EMBL X33 beam line at the DORIS III storage ring (Hamburg, Germany) using a MAR 345 Image Plate detector (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 2 and 8 mg/ml were measured at 10°C. Two successive 120 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
