Discrimination of Saturated Aldehydes by the Rat I7 Olfactory Receptor
BIOCHEMISTRY, 49:6302-6304, AUG 3 2010

The discrimination of n-alkyl-saturated aldehydes during the early stage of odorant recognition by the rat I7 olfactory receptor (OR-I7) is investigated. The concentrations of odorants necessary for 50% activation (or inhibition) of the OR-I7 are measured by calcium imaging recordings of dissociated rat olfactory sensory neurons, expressing the recombinant OR-I7 from an adenoviral vector. These are correlated with the corresponding binding free energies computed for a homology structural model of the OR-17 built from the crystal structure of bovine visual rhodopsin at 2.2 angstrom resolution.
