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 کاملTRIPHOSPHOPYRIDINE NUCLEOTIDE - CYTOCHROME c REDUCTASE IN LIVER
In yeast the reduction of ferricytochrome c by reduced triphosphopyridine nucleotide (TPNH2) is catalyzed by a flavoprotein, cytochrome c reductase, which contains flavin mononucleotide (FMN, riboflavin phosphate) as the prosthetic group (1). In animal tissue the reduction of ferricytochrome c by TPNHz has not yet been reported, although the reaction with reduced diphosphopyridine nucleotide (D...
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...
