Synchrotron SAXS data from solutions of DH-PH in 50 mM Tris-HCL 150 mM NaCl 1.0 mM DTT, pH 7.5 were collected on the EMBL X33 beam line at the DORIS III storage ring (Hamburg, Germany) using a MAR 345 Image Plate detector (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 0.9 and 4.7 mg/ml were measured 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. The low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
