Oxidative phosphorylation in cardiolipin-lacking yeast mitochondria.
The role of cardiolipin in mitochondrial energy transformation was studied by comparing oxidative phosphorylation in the Saccharomyces cerevisiae cardiolipin synthase null mutant crd1Delta, and in isogenic wild type. Oxygen consumption experiments and membrane potential kinetics during the phosphorylation cycle in isolated mitochondria indicated that the absence of cardiolipin causes only a mod...

متن کاملOxidative phosphorylation with endogenous substrates of mitochondria.
During recent studies of oxidative phosphorylation in rat liver mitochondria (2, 3)) we observed that preparations isolated with meticulous care catalyzed a significant uptake of inorganic orthophosphate in the absence of any added substrate. Although incidental observations of endogenous activity of isolated mitochondria have been noted by others (P9), no extensive study of this phenomenon has...
متن کاملOxidative phosphorylation in ascites tumor mitochondria.
tion. Particulate fractions are obtained by the usual centrifugation procedures. The capacity of the isolated mitochondrial fraction to undergo oxidative phosphorylation was investigated. Mitochondria were found to be active with the sub strates succinate, malate, and glutamate, and P/O ratios approaching the theoretical were obtained. The use of malonate in conjunction with glutamate oxidation...
متن کاملThe effect of ribonuclease on oxidative phosphorylation by mitochondria.
In current studies in this laboratory on the composition and activity of plant mitochondria as a function of growth, it has been noted that well washed mitochondrial preparations contain about 1 per cent of the dry weight as ribonucleic acid. Most of this RNA may be due to microsomal contamination, for electron micrographs show corn mitochondrial preparations to be quite heterogeneous (1). Howe...
