Fig. (2a).
Figure shows the ligand trans-2-octenal (labeled) in the minimized docked position in the binding region of rat OR I7. The key distances show a strong electrostatic interaction between the ligand carbonyl group and the Lys164. The positions of F205 and F262 are also shown. Simulations showed that the phenylalanines did not impact the transit pathway of the ligand through the receptor.
