Synchrotron SAXS data from solutions of the DNA repair protein XRCC1 - DNA Ligase IIIα complex in 50 mM Tris-HCl, pH 7.5, 100 mM NaCl, 5 mM MgCl₂, 0.2 mM PMSF, 1 mM benzamidine, 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 2.1 m and at a wavelength of λ = 0.1127 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 50.00 μl sample at 4 mg/ml was injected at a 0.50 ml/min flow rate onto a Shodex LW-803 column at 20°C. 600 successive 3 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.
