Synchrotron SAXS data from solutions of KIX domain (kinase-inducible domain interacting domain) of CREB-binding protein (Mus musculus), mutation L664C in 25 mM Hepes, 150 NaCl, 1 mM DTT, 5% Glycerol, pH 7.2 were collected on the EMBL P12 beam line at the PETRA III storage ring (Hamburg, Germany) using a Pilatus 2M detector at a sample-detector distance of 3 m and at a wavelength of λ = 0.124 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.72 mg/ml was measured at 10.1°C. 30 successive 0.045 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.
