Synchrotron SAXS data from solutions of Phosphorylated (T495) Heat shock cognate 71 kDa protein (Hsc70) T204A apo (5 mg/ml) in 20 mM HEPES, 150 mM KCl, 10 mM M gCl2, 1mM TCEP, pH 7.5 were collected on the EMBL P12 beam line at the PETRA III storage ring (DESY; Hamburg, Germany) using a Pilatus 6M detector at a sample-detector distance of 3 m and at a wavelength of λ = 0.123979 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.00 mg/ml was measured at 20°C. 40 successive 0.095 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.
