Extended Data Fig. 2: Global context of components discussed in the manuscript.

(a) Context of the periplasmic scaffold focussed refinement map (EMD-16724) in the context of the whole motor map (EMD-16723). (b) Structure of the periplasmic scaffold density in isolation. (c) Location of one asymmetric unit from the 17-fold-symmetric periplasmic scaffold in pink as depicted in Figs. 2a, 3a, 4a, and 6. (d) Innermost basal disk ring of 51 FlgP as depicted in Fig. 2. (e4) Innermost basal disk ring of 51 FlgP and innermost medial disk ring of 17 PflC1 as depicted in Fig. 3c. (f) Innermost basal disk ring of 51 FlgP and medial disk lattice of 17 PflC1–7 as depicted in Fig. 3d, f. (g) Proximal disk of 17 PflAB FliL4 as depicted in Fig. 4b, c.
