A, ¹⁵N chemical shift difference for backbone amides between major and minor state of apoSUMO1 from global fits of CPMG relaxation dispersion curves plotted versus ¹⁵N chemical shift difference between apo- and SIMPX-bound states. B, ¹⁵N chemical shift difference for backbone amides between the major and minor state of SIMPX-bound SUMO1 from global fits of CPMG relaxation dispersion curves plotted versus ¹⁵N chemical shift difference between apo- and SIMPX-bound states. C, ¹⁵N chemical shift differences for backbone amides between major and minor state from global fits of CPMG relaxation dispersion curves for apo- and ZZ domain-bound SUMO1 plotted in a covariance graph.
