Figure 3. Radial sections of the empty and full OmRV particles.

Radial sections in the 3D density of the empty (white) and full (yellow) particles, which are shown at radiuses of 170, 179, 188, 197, 206, and 215 Å. The boomerang-shaped raised ridge domains of subunits and the obstructed pore are outlined with light blue and red dotted lines, respectively. The full and empty structures were rendered at an isodensity contour level of 2.1 σ and 2.6 σ, respectively.
