Synchrotron SAXS data from solutions of Complex of Met receptor with InlB in 25mM Na-phosphate buffer, 150 mM NaCl, 1mM DTT, pH 7.5 were collected on the EMBL X33 beam line at the DORIS III, DESY storage ring (Hamburg, Germany) using a 1D Gas detector detector at a wavelength of λ = 0.15 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 2 and 40 mg/ml were measured . 15 successive 60 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.
