Figure 8.

(A) The nucleocapsid orientated down a two-fold axis, showing a cut through the outer two layers and the first shell of dsRNA. The outer shell is the P4-P8 layer, but in this cut view, only the P8 layer is visible (green). The capsid shell is composed of the P1_A (blue) and P1_B (red) proteins. (B) The five dsRNA shells. (C) Two P1 subunits and 10 P8 monomers fitted into a reconstruction of the nucleocapsid. (D) As in C but without the density. The arrow points to the P4 C-terminal tail (pink) bound to the two P1 subunits [68].
