Fig. 2

Open particles of echovirus 18 lacking one, two, or three adjacent pentamers. ac Asymmetric three-dimensional reconstructions of open particles lacking one (a), two (b), or three (c) pentamers. The electron density maps are rainbow colored based on the distance of the electron density surface from the particle center. df Electron density distributions in central sections of asymmetric reconstruction of open particles missing one (d), two (e), or three (f) pentamers. The directions of five-fold, two-fold, and three-fold symmetry axes are indicated. Diffuse density in the areas of the missing pentamers probably belong to the average of the RNA molecules escaping from the particles. Example reference-free two-dimensional class averages of final three-dimensional refinement with C1 symmetry of open particles missing one (g), two (h), or three (i) pentamers. Scale bar represents 10 nm
