Synchrotron SAXS data from solutions of Senescence-associated E3 ubiquitin ligase 1, 0.6 mg/ml in 50 mM Tris, 250 mM NaCl, pH 9 were collected on the EMBL P12 beam line at the PETRA III storage ring (Hamburg, Germany) using a Pilatus 2M detector at a sample-detector distance of 3 m and at a wavelength of λ = 0.123987 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 0.60 mg/ml was measured at 10°C. 20 successive 0.050 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.

Monomer:dimer:tetramer fractions by volume: 52:31:17. The rigid bodies used for the SASREF MX tetramer model were predicted by I-TASSER.
