Dreesen TD, Koch RB: Odorous chemical perturbations of (Na+ + K+)-dependent ATPase activities. Biochem J. 1982 Apr 1;203(1):69-75.
Effects on native and lipid-substituted preparations from individual turbinals from dog olfactory tissue.. Individual turbinals from the right and left sides of dog olfactory tissue were removed and nerve-ending-particle preparations were prepared. (Na+ + K+)-dependent ATPase activities of the individual preparations, and the effect of several odorous compounds [including (+)- and (-)-carvone] on the (Na+ + K+)-dependent ATPase activities, were determined. The maximally stimulatory odorant concentration in the reaction mixture for the majority of odorants was found to be 1.0 mM. Matched pairs of left/right turbinals showed a lack of bilateral symmetry of response. (Na+ + K+)-dependent ATPase activities of various dog brain nerve-ending particle preparations responded only slightly to 1.0 mM odorants. The role of phospholipids in the (Na+ + K+)-dependent ATPase activity was found to be critical. Partial replacement of endogenous lipid with either synthetic phospholipids or extracted lipids resulted in changes in stimulation obtained with endogenous lipids alone. |
