Abstract

To test the hypothesis that olfactory receptors (ORs) recognize different molecular features of odor molecules termed “odotypes”, we studied receptor–ligand interactions of two human and two mouse ORs, recognizing (−)citronellal. Structurally similar receptors provide identical binding pockets (OLFR43, OR1A1, and OR1A2), and have comparable EC50 values. Other ORs with lower sequence identity bind (−)citronellal in a different way, leading to different EC50 values.
