Figure 3. Inline graphic5 to Inline graphic10 defined from the rotameric switches in TM4, TM5, TM6, and TM7.

Figure 3

Rotameric states of (a) W129, (b) Y197, (c) CWxP motif, and (d) NPxxY motif are compared for the apo (white), antagonist-bound (cyan), and agonist-bound (pink) forms. (e) Helix bending in TM7. The helix bending angle (bendix) of TM7 was calculated using bendix program [45]. The helix is displayed as a cylinder marked with the heatmap ranging from 0o to 20o. The scatter plot on right side depicts the relationship between H-bond of N280-S281 and the bending angle of the TM7 helix (apo: black, antagonist-bound: blue, agonist-bound states: red). The average bending angles are annotated with the symbols, X.
