Synchrotron SAXS data from solutions of Lyz in Sodium Acetate in 40 mM Sodium Acetate, pH 3.8 were collected on the EMBL X33 camera at the DORIS III storage ring (Hamburg, Germany) using a Pilatus 1M-W detector at a sample-detector distance of 2.7 m and at a wavelength of λ = 0.15 nm , the range of momentum transfer 0.087 < s < 17.690 nm-1 was covered (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 8.09 mg/ml was measured at 10°C. Eight successive 15 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 concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
