Figure 4. Close-up surface views of the OmRV capsid.

(A) Close-up view around the 5-fold axis in the empty particle. Arrows indicate regions of interaction between subunits or between a subunit and the obstructed pore. The boomerang-shaped raised ridge domains of subunits and the obstructed pore are outlined with light blue and red dotted lines, respectively. (B) Cross-sections of the empty (white) and the full (yellow) particles at the 5-fold axis. White arrows indicate the obstructing plug at the 5-fold axes. The full and empty structures were rendered at an isodensity contour level of 2.1 σ and 2.6 σ, respectively.
