Synchrotron SAXS data from solutions of DNA-binding protein HU-alpha (E34K mutant) bound to 80 bp DNA in 10 mM Bis-Tris, 50 mM NaCl, pH 5.5 were collected on the 12.3.1 (SIBYLS) beam line at the Advanced Light Source (ALS; Berkeley, CA, USA) using a Pilatus3 X 2M detector at a sample-detector distance of 1.5 m and at a wavelength of λ = 0.103 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). 300 successive 3 second frames were collected at 10°C. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
His curve is part of a pH series. Increasing the pH removes aggregation presumably due to protein surface charge changes. The SAXS data for this entry is measured from aggregated material and therefore the Rg and I(0) parameters do not apply.
