The mitochondrial respiratory chain.
In the present chapter, the structures and mechanisms of the major components of mammalian mitochondrial respiratory chains are reviewed. Particular emphasis is placed on the four protein complexes and their cofactors that catalyse the electron transfer pathway between oxidation of NADH and succinate and the reduction of oxygen to water. Current ideas are reviewed of how these electron transfer...
متن کاملThe Electron Transport System of Hydrogenomonas eutropha
Wosilait and Nason (1) demonstrated that quinones could serve as electron acceptors for the enzymatic oxidation of reduced pyridine nucleotides, and their survey of plant, animal, and microorganism extracts (2) revealed the general occurrence of reduced pyridine nucleotide-quinone reductase activity. This finding and Dam’s (3) earlier report, which indicated that vitamin K was a common constitu...
متن کاملFactors affecting the synthesis and degradation of ribulose-1,5-diphosphate carboxylase in Hydrogenomonas facilis and Hydrogenomonas eutropha.
Hydrogenomonas facilis and H. eutropha cultured in fructose medium retained high levels of ribulose-1,5-diphosphate carboxylase only when the following conditions were fulfilled: low aeration, FeCl(3) addition to fructose medium, and cell harvest at or prior to mid-exponential phase of growth. Repression of carboxylase synthesis was demonstrated under conditions of high oxygen tension during gr...
متن کاملMixotrophic growth of Hydrogenomonas eutropha.
Mixotrophic growth conditions were established by the addition of lactate to cultures of Hydrogenomonas eutropha growing autotrophically in a gaseous environment of H(2), O(2), and CO(2) (6:2:1). The specific growth rate of mixotrophic cultures was double that of the autotrophic cultures, and lactate disappearance paralleled growth. Growth yields in mixotrophic cultures were significantly great...
متن کاملRespiratory chain of Streptomyces.
There is currently a great deal of interest in the streptomyces as producers of antibiotics, but relatively little is known about the mechanisms of intracellular energy supply in this group of organisms. They are aerobes, and carbohydrates serve as an energy source. There is good evidence that the pathways of carbohydrate metabolism in the streptomyces include the glycolysis sequence (Cochrane,...
