Electron micrographs and icosahedral reconstructions of CVA9 in complex with integrin. (A and B) Micrographs of CVA9 capsid alone (1.6-μm underfocus) and in complex with integrin αvβ6 (3.0-μm underfocus), respectively. In panels A and B, a white arrow indicates an empty particle and a black arrow indicates a filled particle. Bar, 100 nm. (C and D) Radially depth-cued isosurface representations of the filled CVA9 capsid (C) and filled CVA9 capsid-integrin αvβ6 complex (D) filtered to 10.3-Å resolution. (E and F) Radially depth-cued isosurface representations of the empty CVA9 capsid and empty CVA9 integrin αvβ6 capsid filtered to 9.9-Å resolution. In panels C to F, the view is down a 2-fold axis of symmetry. The scale bar is for the radial depth cueing. (G) Radial profiles for the empty CVA9-integrin αvβ6 complex (line with black dashes), filled CVA9-integrin αvβ6 complex (line with black dashes and dots), empty CVA9 capsid (solid line), and filled CVA9 (dotted line) (one pixel is 1.13 Å).
