experiment_descriptionSynchrotron SAXS data from solutions of Halobacterium salinarum VNG0258H/RosR in 50 mM HEPES, 2 M NaCl, 0.02% NaN3, pH 7 were collected on the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.09919 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 8.00 mg/ml was measured at 25°C. 10 successive 2 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.

One solute concentration of 8.00 mg/ml was measured at 25°C. 10 successive 2 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.",
