Data were normalised to protein concentration and the high angle data from highest concentration and low angle data from lowest concentration were merged to generate final SAXS profile. Because of the flexibility of linear-tetraubiquitin molecule, ensemble optimisation method, EOM, was performed. The models shown above are two tetraubiquitin examples from the final EOM output. All EOM models, the radius of gyration distribution and maximum particle dimension distribution can be found in the full entry zip archive.",
