a Overall structure of a hexon at the side view. Two adjacent MCP–SCP heterodimers are shown as cartoon models and the other four are shown as white surface models. One MCP is colored by domains and the other adjacent protomer is colored in cyan. The SCPs are colored by chains. b Top view of the hexon capsomer, revealing the contacting network of SCPs. c Bottom view of the basal floor interaction network in a hexon. d–f Architecture and inter-protomer interactions of a penton, shown in similar views and color schemes to those of the hexon in (a–c). g Superposition of the MCP conformers in hexon and penton capsomers. The insets show the close-up views of distinguished structural motifs with different conformations. The unresolved regions are represented by dashed lines.
