Cryo-EM reconstruction of EspB2-287 heptamer complex. (A–B) Density map and structural model made with ChimeraX (Goddard et al., 2018), showing each monomer in different colours. For (A) and (B), the upper panels show the top views and the bottom panels show the side views. Representation of the smallest inner-diameter calculated by HOLE (Smart et al., 1993). (C) Model and densities of intramolecular interaction at W176–Y81 and intermolecular interaction at Q48-Q164. Colours follow the conventional colouring code for chemical elements.
