Synchrotron SAXS data from solutions of 0.3mM K63-diUb in 100mM NaCl, 10mM sodium acetate, pH 6 were collected on the BL19U2 camera on the storage ring Shanghai Synchrotron Radiation Facility (SSRF) (Shanghai, China). Using a Pilatus 1M detector at a sample-detector distance of 2.1 m and at a wavelength of λ = 0.1033 nm one solute concentration of 5.1 mg/ml was measured at 25°C. 20 successive 1 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 angular range between 0.271 and 2.282 1/nm was used for PDDF conversion.
