Fig. 3

View of the disordered segment in the hook and in the rod. a Overview of the hook from C. jejuni in grey with six highlighted molecules of FlgE. b Zoom-up, stereo view of the core domain of the hook with the disordered segment, represented with spheres, surrounded by molecules of FlgE which it interacts with. Comparative view of domains D0 and D1 of the hook of C. jejuni (c), namely the hook and the distal rod of S. enterica in (d) and (e), respectively. The molecules that make the hook and the rod are colored in grey with one molecule colored in green and its disordered segment colored in purple. The upper panels in (c), (d) and (e) show a projection from the distal end. In each case, one molecule is colored in green with the ID-Rod-Stretch represented in magenta.
