Figure 2: Insights into the structure of CHIVs.
From: Chimeric viruses blur the borders between the major groups of eukaryotic single-stranded DNA viruses
(a) Structure of the MNSV (PDB ID:2ZAH) is shown to illustrate the contribution of the distinct CP domains to the virion organization and the position of these domains in the capsid surface lattice. The P-domain, magenta; S-domain, green; R-domain, cyan. On the right is a zoom-in on one of the capsid areas, where locations of the conserved insertions present in the CPs of CHIVs, as well as viruses SmV-A and PhV-A are indicated with orange spheres. (b) Structure of the MNSV CP. The P-, S- and R-domains, as well as the locations of conserved insertions are coloured as in a. In addition, the locations of species-specific sequence insertions present in the CPs of only some CHIVs are indicated with grey spheres. (c) Structural model of the CHIV10 CP. The colouring represents sequence conservation among CHIV CPs (red, least conserved; blue, most conserved).
