Fig. 3. Various slices through the three-dimensional map. (A–C) Orthogonal slices through the three-dimensional map, which are 0.44 nm apart. (B) Represents an equatorial slice. The symmetry axes are indicated in white in one quadrant of the map. (D–I) Spherical slices spaced by 1.32 nm, starting at an inner radius of 6.6 nm. Some of the fuzzy globules at the two-fold symmetry axes are indicated by arrowheads.
