Figure 3
Cryo-EM reconstruction of CPV at 21 Å resolution showing (a) a surface-shaded representation (adapted from Chipman et al., 1996) and (b) a central section (adapted from Tsao et al., 1991). The virus is about 280 Å in diameter. These reconstructions were based on icosahedral symmetry averaging, as was also the determination of the CPV crystal structure. |
