FIG. 3.

Topographic comparison of the PstDNV protein capsid with other parvoviruses. Surface renderings of 3D density maps of PstDNV, GmDNV, and CPV at 8-Å resolution, generated from atomic coordinates. One icosahedral asymmetric unit is indicated by a black triangle. The surface is colored according to the distance from the viral center (100 Å [blue], 107.5 Å [cyan], 115 Å [green], 122.5 Å [yellow], and 130 Å[red]). In the top right corner of the figure, a combination display of the equatorial slices of the density maps depicts the differences in thickness and expansion of the protein shells. The positions of icosahedral symmetry axes are indicated by the numbered gray arrows.
