Correction to: A suite of 19F based relaxation dispersion experiments to assess biomolecular motions Jan H. Overbeck1 · Werner Kremer1 · Remco Sprangers1 Published online: 25 November 2020 © Springer Nature B.V. 2020

Correction to: Journal of Biomolecular NMR https​://doi.org/10.1007/s1085​8-020-00348​-4

The original article has been corrected.

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. anti-ringing φ5

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 experiPublisher’s Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
