15N R relaxation dispersion profiles for GB1 in complex with IgG. Experiments were acquired at 700 MHz (16.4 T) with 2 mM Gd(DTPA-BMA) and 850 MHz (20 T) with 5 mM Gd(DTPA-BMA), and a sample temperature of 300 ± 2 K. Best fit curves to a two-site exchange model assuming a common motion are shown as orange lines (kex = 13 ± 3 × 103 s−1). Residue specific φex (×103 rad2 s−2) and R1ρ,0 (s−1) are indicated in each plot.
