Figure 3: Structural superposition of modeled 154 variants and cleaved NS.

(a) Superposition of WT NS (black), W154A (green) and W154P (red) after 40 ns simulation. (b) Superposition of the cleaved NS (yellow) and W154P (red) showing the shortening of helix F at its N-terminal end and movement of the hydrophobic residues. The images were generated using PyMOL48.
