Largest and smallest complete viral particles solved by X-Ray crystallography. Both structures are reprented here to scale. The larger structure is simian virus 40 (PDB entry 1SVA, Stehle et. al. 1996), a Polyomavirus from the Papovaviridae family. The non-enveloped icosahedral particles, ~45 nm in diameter contains the circular dsDNA genome. 72 pentameric capsomers are arrange on a T=7d icosahedral lattice, 12 strict pentamers at the icosahedral vertices have only 5 neighbouring capsomers while the other and 60 pentameric capsomers are arranged in hexamers. View is along an icosahedral 2-fold axis of symmetry.

The small structure is that of satellite tobacco necrosis virus (PDB entry 2STV, Unge et. al. 1980). The non-enveloped icosahedral particles, ~17 nm in diameter contains the linear ssRNA genome. 60 proteins are arranges on a T=1 icosahedral lattice. View is along an icosahedral 5-fold axis of symmetry.
