Fig. 1.

Ribbon representations of the VSV nucleocapsid in complex with the C-terminal N protein-binding domain of the P protein (P_CTD). (A) Three assembled N molecules are represented in red, green, and blue. P_CTD, shown in yellow, binds to the extended loop (C loop) within the C lobe of 2 adjacent N molecules (red and green). (B) Scaled-up image of the interaction. Residues of the dual N-binding site that are in contact with P_CTD are shown. The illustrations found in this and the subsequent figures were generated with PyMOL (41).
