Correction to: A suite of 19F based relaxation dispersion experiments to assess biomolecular motions

Abstract

In the original publication, Figures 3 and 6 were displayed incorrectly due to a mistake made by the publisher. The correct version of Figs. 3 and 6 are given below.

Fig. 3

¹⁹F on-resonance R_1ρ experiment. a Pulse sequence for the ¹⁹F on-resonance R_1ρ experiment. Narrow (wide) rectangles indicate 90° (180°) pulses, which are applied along the x-axis unless indicated otherwise. The phase cycle is φ1 = x, φ2 = [− x, x], φ3 = [x, x, − x, − x, y, y, − y, − y], φ4 = [y], φ5 = [− y], φ_rec = [x, − x, − x, x, y, − y, − y, y]. b On-resonance R_1ρ relaxation dispersion profiles for W7 and W29. The size of the error-bars correspond to 1 standard deviation

Fig. 6

¹⁹F Relaxation dispersion experiments of the 360 kDa α₇α₇ double heptamer. a Model of the double heptameric α₇α₇ complexes with 14 BTFA labeling sites at position 18C (purple) of each subunit. Position 35 that does not show exchange (Fig. S8) is indicated in cyan. The model of the complex is based on the structure of the 20S proteasome from T. acidophilum (PDB ID 1PMA). b CPMG experiments from 293 to 323 K. c On-resonance R_1ρ experiments from 293 to 323 K. d Plot of exchange rates against temperatures as derived from the global fit of all RD data. e Logarithmic plot of kinetic rates against inverse temperature. f Schematic presentation of ΔG, ΔH and TΔS changes from the ground state GS to the excited state ES via a transition state TS
