SAXS data from solutions of Glucosidase/Rutinosidase (glycosylated) in 50 mM sodium citrate, 150 mM NaCl, pH 4.5 were collected using an Anton Paar SAXSpoint 2.0 instrument at the Institute of Biotechnology, Czech Academy of Sciences/Centre of Molecular Structure (Vestec, Czech Republic) equipped with an Eiger R 1M detector at a sample-detector distance of 0.8 m and at a wavelength of λ = 0.134 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 1 and 7 mg/ml were measured at 20°C. 60 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 concentrations were extrapolated to infinite dilution and merged with the higher concentration data to yield the final composite scattering curve.
