SAXS data from solutions of salt stress-induced protein in 50 mM NaCl, 2.7 mM KCl, 10 mM Na2HPO4, 1.8 mM KH2PO4, pH 7.4 were collected using an Anton Paar SAXSpace instrument (CSIR - Institute of Microbial Technology (IMTech), Chandigarh, India) equipped with a Mythen 1K detector at a sample-detector distance of 0.3 m and at a wavelength of λ = 0.15418 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 11.00 mg/ml was measured at 10°C. Three successive 600 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.
