Synchrotron SAXS data from solutions of Nucleoplasmin-like domain-containing protein PfNPM (1-170) - H2A/H2B histone oligomer complex in 20 mM Tris, 150 mM NaCl, 2 mM β-mercaptoethanol, pH 7.5 were collected on the BM29 beam line at the ESRF storage ring (Grenoble, France) using a Pilatus3 2M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.09794 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. 10 successive 20 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.
