Inhibition of cytochrome c oxidase by sulphide.
of the detergents used (Evans, 1956), although the sharp cut-off in activity evident lends support to the idea that protein denaturation by anionic detergents involves the formation of protein-detergent micelles (Tanford, 1970). The most effective inhibitor of glucuronidase activity was sodium tridecyl sulphate, whereas sodium pentadecyl sulphate exerted the strongest effects on the sulphatase....
متن کاملCytochrome c-mediated electron transfer between ubiquinol-cytochrome c reductase and cytochrome c oxidase. Kinetic evidence for a mobile cytochrome c pool.
Ubiquinol oxidase has been reconstituted from ubiquinol-cytochrome c reductase (Complex III), cytochrome c and cytochrome c oxidase (Complex IV). The steady-state level of reduction of cytochrome c by ubiquinol-2 varies with the molar ratios of the complexes and with the presence of antimycin in a way that can be quantitatively accounted for by a model in which cytochrome c acts as a freely dif...
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 کاملQuantitative resolution of succinate-cytochrome c reductase into succinate-ubiquinone and ubiquinol-cytochrome c reductases.
A purified, active succinate-ubiquinone reductase was prepared from succinate-cytochrome c reductase without damage to ubiquinol-cytochrome c reductase by 1.1% Triton X-100 solubilization at pH 8.0, and calcium phosphate column chromatography in 50 mM Tris-succinate buffer, pH 8.0, containing 30 mM potassium phosphate. Succinate-ubiquinone reductase thus obtained contains ubiquinone and catalyz...
متن کاملEffect of specific lysine modification on the reduction of cytochrome c by succinate-cytochrome c reductase.
The reduction of cytochrome c by succinate-cytochrome c reductase was studied at very low cytochrome c concentrations where the reaction between cytochrome c1 and cytochrome c was rate limiting. The rate constant for the reaction was found to be independent of ionic strength up to 0.1 M chloride, and to decrease rapidly at higher ionic strength, suggesting that the interaction between cytochrom...
