FIG. 4.
Shaded-surface representations of ADVG-VP2 (A), CPV (B), and B19 (C), all viewed down a twofold icosahedral axis of symmetry. Panels A and C show the 3D cryo-EM reconstruction of ADVG-VP2 and B19 VP2 capsids (25) to 22 and 26 Å resolution, respectively, and panel B shows the atomic structure of CPV (63), rendered at 21 Å resolution. Locations of some two- (2), three- (3), and fivefold (5) icosahedral axes are indicated.
