Backbone RMSF and IscU motion within the ternary complex. (A) Average structure of the IscS-IscU hetero-tetramer from the ternary complex simulation, depicted as ribbons and colored according to backbone RMSF values, from lowest (blue) to highest (red). Ribbon thickness is proportional to RMSF value. (B) IscU protomer motions around the IscS dimer from the ternary complex simulation. Details described in the caption of Fig. 4D.
