Fig. 1: Dynamics of FAST/N871b complex.

a The NMR-derived spatial structure of FAST/N871b is colored according to the generalized order parameters (S2) of NH bonds (pink and red, ps-ns motions) and exchange contributions to the transverse relaxation (Rex, blue, µs-ms motions). b The resulting FAST/N871b structure after 100 ns MD simulations is colored according to the magnitudes of atom B-factors. Blue and red correspond to relatively stable and mobile regions, respectively.
