Synchrotron SAXS data from solutions of Collagenase H C-terminal non-catalytic segments Polycystic Kidney disease domain 2 (PKD2) and Collagen binding domain (CBD) bound to triple helical collagen like-peptide [(POG)10]3 in 50 mM HEPES, 100 mM NaCl, 5 mM CaCl2, pH 7.5 were collected on the 12.3.1 (SIBYLS) beam line at the Advanced Light Source (ALS) storage ring (Berkeley, CA, USA) using a Pilatus3 X 2M detector at a sample-detector distance of 1.5 m and at a wavelength of λ = 0.1127 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 4 and 6 mg/ml were measured at 10°C. 50 successive 0.300 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. The low angle data collected at lower concentrations were extrapolated to infinite dilution and merged with the higher concentration data to yield the final composite scattering curve.
