The RV-C have been refractory to structure determination because they are difficult to propagate in vitro. Here, we report the cryo-EM atomic structures of the full virion and native empty particle (NEP) of RV-C15a. The virus has 60 "fingers" on the virus outer surface that probably function as dominant immunogens. Because the NEPs also display these fingers, they may have utility as vaccine candidates. A sequence-conserved surface depression adjacent to each finger forms a likely binding site for the sialic acid on its receptor. The RV-C, unlike other EVs, are resistant to capsid-binding antiviral compounds because the hydrophobic pocket in VP1 is filled with multiple bulky residues. These results define potential molecular determinants for designing antiviral therapeutics and vaccines.
