Synchrotron SAXS data from solutions of MenV phosphoprotein, amino acids 209-388 in 12.5 mM MOPS/KOH pH 7.0, 250 mM NaCl, pH 7 were collected on the SAXS/WAXS beam line at the Australian Synchrotron (Melbourne, Australia) using a Pilatus 1M detector at a sample-detector distance of 1.4 m and at a wavelength of λ = 0.103 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 4.80 mg/ml was measured at 20°C. 25 successive 1 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.
