Figure 3
Structure of the RRV nucleocapsid core. (a) Surface-shaded twofold view of the virion reconstruction after all densities outside a radius of 210 Å were removed. The pentamer and hexamer arrangements of the nucleocapsid subunits are visible. (b) Depth-cued representation of the map in (a) with superimposed T = 4 lattice. One icosahedral asymmetric unit lies within the triangle (red) bounded by two threefold axes and one fivefold axis. It includes four monomers (A1, B1, C1 and D1). Yellow numbers identify the icosahedral axes and green symbols label the pseudoaxes. The polar angles are defined as in Rossmann & Blow (1962BB28). [Reprinted by permission from Cheng et al.
