a, Gold-standard Fourier shell correlation (FSC) curve of RELION-postprocessed rod C1 map. Resolution at the gold-standard cutoff (FSC = 0.143) is indicated. Curves: red, phase-randomized; green, unmasked; blue, masked; black, corrected. b, Local resolution estimates (in Å), as calculated by RELION3.1 LocalRes. c, Representative modelled protein densities. d, Interaction of FliE (green cartoon and surface) with FliP of the Export Gate (blue cartoon). e, Overlay of a full FliE subunit (FliE-b) with FliE-a, demonstrating the overlap with the position of the FliR N-terminus. f, Overlay of representative rod subunits demonstrates the conserved core and variation in inserted domains (subunits colored as in Fig. 2).
