Influence of metallic chelates on the diphosphopyridine nucleotide oxidase and diphosphopyridine nucleotide-cytochrome c reductase systems.
The need for additional study on the specific relation between metallic ions and metabolic function, especially in the case of the diphosphopyridine nucleotide oxidase system, has been expressed by Mahler (1) and others. This is particularly indicated in view of the fact that a number of the known components of this system contain iron. While it is broadly concluded that iron compounds facilita...

متن کاملAssociation of Reduced Diphosphopyridine Nucleotide Cytochrome C Reductase Activity with Meningopneumonitis Virus
DPNH cytochrome c reductase activity has been found associated with the MP virus isolated from the infected allantoic fluids or yolk sacs of fertile eggs and treated with trypsin, perfringens toxin, and cobra venom. The corresponding normal tissue enzymes can be nearly completely destroyed by such treatment, also the small activity found in crude preparations of influenza virus is destroyed by ...
متن کاملEffects of digitonin and tocopherol on bovine heart muscle reduced diphosphopyridine nucleotide- and succinate-cytochrome c reductase and cytochrome c oxidase.
The effects of digitonin and tocopherol on bovine heart reduced diphosphopyridine nucleotideand succinate-cytochrome c reductases and cytochrome c oxidase have been studied with the following results. 1. Low concentrations of digitonin stimulate succinateand DPNH-cytochrome c reductase and cytochrome c oxidase. Higher concentrations of digitonin completely inhibit cytochrome c reductases, while...
متن کاملThe preparation and properties of a soluble diphosphopyridine nucleotide cytochrome c reductase.
The transfer of electrons from the pyridine nucleotide-linked dehydrogenases to cytochrome c is mediated by a class of enzymes which has been termed the cytochrome c reductases (1). Two TPNH cytochrome c reductases, both flavoproteins, have been purified, one by Haas et al. (1) from yeast, and another by Horecker (2) from liver.’ Analogous enzymes in the case of DPNH have been implicated in par...
