Buried surface areas of interfaces within AiV-1 and CVA16 virions and empty particles. (A) List of buried surface areas. Individual subunits are labeled according to their relative positions shown in panel B. “Other*” indicates the sum of buried surface areas of additional small interfaces. (B) Capsid surface representation of AiV-1 virion with subunits VP0, VP1, and VP3 shown in green, blue, and red, respectively. Icosahedral asymmetric units considered for buried surface calculations are labeled with letters.
