Interactions within and between VP1 subunits. a The cryo-EM density (mesh) and corresponding model (sticks) of VP1 are shown. In addition to the positively charged residues at the N (Lys9) and C (Arg79) termini and the putative glycosylation site at Asn47, key residues involved in intramolecular interactions are labeled. b Two VP1 molecules are rendered as a ribbon in orange and blue. Residues involved in intermolecular contacts between two neighboring VP1 subunits are labeled. These residues create multiple hydrophobic contacts and a large interface
