Fig. 3.

Stereoview detailing the AR1–λN(34–40) interaction. The backbone ribbons of the AR1^A and AR1^B molecules are in blue and cyan, respectively. Residues interacting specifically with the peptide are shown as sticks and are color-coded by atom type (gray, carbon; red, oxygen; blue, nitrogen). The λN peptide is drawn as a stick figure (pink, carbon). Three water molecules, which are mediating interactions, are shown as green spheres. Hydrogen bonds or salt bridges discussed in the text are indicated as dashed lines.
