Oxidative phosphorylation in mitochondrial fragments obtained by sonic vibration.
Until recently, progress in our understanding of the mechanism of oxidative phosphorylation in mammalian tissues has been hampered in large measure by the inability to observe the process in units simpler than intact mitochondria. The first well characterized phosphorylating submitochondrial system prepared by digitonin treatment of liver mitocondria has been extensively described by Cooper and...
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...

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 extracts of Rhodospirillum rubrum.
The purple photosynthetic bacterium, Rhodospirillum rubrum, grows anaerobically only when illuminated with light of appropriate wave lengths. Extracts prepared from cells grown in this manner catalyze an anaerobic light-dependent phosphorylation of adenosine diphosphate to adenosine triphosphate (1). However, R. rubrum also can be grown heterotrophically in darkness if oxygen is provided (2). U...
