Abstract

Substitution of potassium cloride for sucrose in the incubation medium of liver mitochondria or addition of magnesium cloride to the sucrose medium produces a small (if any) effect on the palmitate-induced uncoupling and its sensitivity to carboxyatractylate and aspartate, but it exerts a pronounced increase in the recoupling effect of glutamate on this uncoupling. 20-40 microM cetyltrimethyl ammonium bromide increases the recoupling effect of glutamate and aspartate but decreases that of carboxyatractylate. The data are in line with suggestion that both ATP/ADP antiporter and aspartate/glutamate antiporters are involved in the fatty acid-induced uncoupling.
