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.
