Synchrotron SAXS data from solutions of Rabies virus Nishigahara strain Phosphoprotein Isoform 3 (P3) in 25 mM HEPES, 150 mM NaCl, 1 mM TCEP, pH 7.4 were collected on the SAXS/WAXS beam line at the Australian Synchrotron storage ring (Melbourne, Australia) using a Pilatus3 S 2M detector at a sample-detector distance of 3.3 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 5.00 mg/ml was measured at 22°C. One 1 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.
