TRIPHOSPHOPYRIDINE 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 کاملTriphosphopyridine nucleotide linked isocitric dehydrogenase in bacteria.
The conversion of isocitric acid to alpha-ketoglutarate has been demonstrated both in animal tissues (Martius, 1937; Krebs and Johnson, 1937; Adler et al., 1939; Ochoa, 1948) and in yeast (Kornberg and Pricer, 1951; Foulkes, 1951). Triphosphopyridine nucleotide was first implicated as a specific coenzyme for this reaction by Adler et al. (1939). Recently Kornberg and Pricer (1951) found in yeas...
متن کاملDiphosphopyridine Nucleotide - linked Aldehyde Dehydrogenase
In continuation of our investigation of liver diphosphopyridine nucleotide-linked aldehyde dehydrogenase (1)) we have undertaken a study of various classes of inhibitors of the enzyme. Interest in aldehyde oxidation has been increasing in recent years from several points of view. The classical problem of ethanol oxidation in viva still has many unresolved facets (Z), and the enzymes responsible...
متن کاملA triphosphopyridine nucleotide-cytochrome c reductase from heart muscle.
Extensive studies by numerous workers have served to characterize the reduced diphosphopyridine nucleotide and succinic oxidase systems as important enzymatic pathways in the terminal respiratory chain of mammalian tissue [see reviews by Chance (1) and Slater (2)]. These systems have been shown to consist of an integrated complex of components including flavins, various cytochromes, metal ions,...
متن کاملMicrosomal triphosphopyridine nucleotide-cytochrome c reductase of liver.
The biological role of reduced triphosphopyridine nucleotide (TPNH) and the metabolic pathways of its hydrogen atom and electron appear to be fundamentally different from those of reduced diphosphopyridine nucleotide (DPNH). The latter coenzyme appears to be intimately involved in cellular adenosine triphosphate (ATP) production, and is oxidized by both a phosphorylating, antimycin-sensitive pa...
