More Intramitochondrial Bodies
Suzuki and Mostofi (1) have recently reported the The purpose of this note is to point out that very occurrence of a variety of intramitochondrial in-similar striated structures occur in kidney mito-clusions, in the thick limb of the loop of Henle of chondria from rats treated with substances other the rat kidney, after glycerol treatment. than glycerol. During experiments on diuretic
متن کاملIntramitochondrial Filamentous Bodies in the Thick Limb of Henle of the Rat Kidney
"Intramitochondrial filamentous bodies" (IMFB) were occasionally found within the matrix of some mitochondria of the thick limb of Henle of the rat kidney, but not elsewhere in the tubular system. Three types were recognized: type I, an accumulation of filaments 55 A thick; type II, a bundle of parallel filaments having the same thickness as those of type I and regular spacing, 87 A apart, from...
متن کاملIntramitochondrial metabolism of phosphoenolpyruvate.
Phosphoenolpyruvate was formed by rabbit liver mitochondria during incubations in the presence of dinitrophenol with oc-ketoglutarate and with other Krebs cycle intermediates as substrates. These intermediates, as indicated by experiments with labeled compounds, served as precursors for the carbon skeleton of the synthesized phosphoenolpyruvate. The phosphate, in the absence of exogenous supply...
متن کاملIntramitochondrial localization of kynurenine aminotransferase.
Comparisons with the distribution of intramitochondrial marker enzymes have indicated that kynurenine aminotransferase is present in the inner membrane fraction of rat liver mitochondria. It appears to be weakly bound to the inner membrane because it is easily solubilized by increasing the concentration of digitonin. With the use of a-ketoglutarate or oxalacetate as amino group acceptor, the am...
متن کاملIntramitochondrial Fibers with Dna Characteristics
The effects of proteolytic enzymes, ribonuclease, and deoxyribonuclease upon a fibrous component of chick embryo mitochondria, which was previously shown to have many fixation and staining properties characteristic of the bacterial nucleoplasm, are reported. Pepsin digestion of formaldehyde-fixed tissues removed the membranes and matrices of mitochondria, but a pepsin-resistant fibrous material...
