Synchrotron SAXS data from solutions of Collagenase H C-terminal non-catalytic segments Polycystic Kidney disease domain 1 (PKD1), Polycystic Kidney disease domain 2 (PKD2) and Collagen binding domain (CBD) in 10 mM HEPES, 100 mM NaCl, 0.4 mM EGTA, 2.4 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 1 and 3 mg/ml were measured at 10°C. 33 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.
