Synchrotron SAXS data from solutions of M1-linked tetraubiquitin, M1(1-73)-Ub4 in 20 mM sodium phosphate, 0.5 mM EDTA, 0.02 % NaN3, pH 6.8 were collected on the BioCAT 18ID beam line at the Advanced Photon Source (APS), Argonne National Laboratory storage ring (Lemont, IL, USA) using a Pilatus3 X 1M detector at a sample-detector distance of 3.7 m and at a wavelength of λ = 0.1033 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 7.19 mg/ml was measured at 20°C. 21 successive 0.500 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.
