pubmed:abstractText
The ATP/ADP-antiporter inhibitors and ADP decrease the palmitate-induced stimulation of the mitochondrial respiration in the controlled state. The degree of inhibition decreases in the order: carboxyatractylate greater than bongkrekic acid, palmitoyl-CoA, ADP greater than atractylate. GDP is ineffective. The inhibiting concentration of carboxyatractylate coincides with this arresting the state 3 respiration. Carboxyatractylate inhibition decreases when the palmitate concentration increases. Stimulation of controlled respiration by FCCP or gramicidin D at any concentration of these uncouplers is carboxyatractylate-resistant, whereas that by low concentrations of DNP is partially suppressed by carboxyatractylate. These data together with observations that palmitate does not increase H+ conductance in bilayer phospholipid membranes and in cytochrome oxidase-asolectin proteoliposomes indicate that the ATP/ADP-antiporter is somehow involved in the uncoupling by low concentrations of fatty acids (or DNP), whereas that by FCCP and gramicidin D is due to their effect on the phospholipid bilayer. It is suggested that the antiporter facilitates translocation of palmitate anion across the mitochondrial membrane.
