Fig. 4.

The NP-RNA interaction. (A) A magnified side view of the interaction between the BUNV NP and bound RNA. RNA is shown as a colored stick in rainbow colors from the 5′- to 3′-end. The NP polypeptide is shown as a semitransparent cartoon representation with an identical color scheme as that in Fig. 3C. The residues contacting the RNA are shown as colored sticks. (B) Schematic top view of the NP–RNA interactions. The last nucleotide located in the cleft exposed to the solvent between two NP protomers is shadowed. The dashed lines denote the contacts between the RNA and residues.
