SAXS data from solutions of RECQ like helicase 5 fragment in 25 mM HEPES, 200 mM NaCl, 1 mM DTT, pH 7.5 were collected using a Rigaku BioSAXS-1000 instrument at CEITEC (Brno, Czech Republic) equipped with a Rigaku HyPix-3000 detector at a sample-detector distance of 0.5 m and at a wavelength of λ = 0.154 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 1.00 mg/ml was measured at 20°C. One 3600 second frame was collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
