Regulation of Mitochondrial Electron Transport Chain Assembly
Journal of Molecular Biology, 2018Mitochondrial function depends on the correct synthesis, transport, and assembly of proteins and cofactors of the electron transport chain. The initial idea that the respiratory chain protein complexes (RCCs) were independent structures in the inner mitochondrial membrane evolved after the identification of higher quaternary structures called ...

Electron Transport Chain Defects in Heart Failure
Heart Failure Reviews, 2002In recent years, the possibility that disorders of cardiac metabolism play a role in the mechanisms that lead to ventricular dilatation and dysfunction in heart failure has attracted much attention. Electron transport chain is constituted by a series of multimeric protein complexes, located in the inner mitochondrial membranes, whose genes are ...

Regulation of the photosynthetic electron transport chain
Planta, 1999The regulation of electron transport between photosystems II and I was investigated in the plant Silene dioica L. by means of measurement of the kinetics of reduction of P(700) following a light-to-dark transition. It was found that, in this species, the rate constant for P(700) reduction is sensitive to light intensity and to the availability of CO(2).

Branched Electron Transport Chain in Trypanosoma mega
Nature New Biology, 1972THE life cycle of certain pathogenic African trypanosomes is characterized by a striking change in the mechanism of oxidative reactions on which the aerobic metabolism of the organism depends. Vertebrate bloodstream forms of Trypanosoma brucei group trypanosomes apparently depend on a non-mitochondrial, cyanide-insensitive α-glycerophosphate oxidase ...

Electron transport chain in a thermotolerant yeast
Journal of Bioenergetics and Biomembranes, 2017Yeasts capable of growing and surviving at high temperatures are regarded as thermotolerant. For appropriate functioning of cellular processes and cell survival, the maintenance of an optimal redox state is critical of reducing and oxidizing species.

Mobility in the mitochondrial electron transport chain
Biochemistry, 1985The role of lateral diffusion in mitochondrial electron transport has been investigated by measuring the diffusion coefficients for lipid, cytochrome c, and cytochrome oxidase in membranes of giant mitoplasts from cuprizone-fed mice using the technique of fluorescence redistribution after photobleaching (FRAP).

ELECTRON TRANSPORT THROUGH MOLECULAR CHAINS
Nano, 2007We study electron transport through molecular chains attached with two nonsuperconducting electrodes by the use of Green's function technique. Here, we do parametric calculations based on the tight-binding model to characterize the electron transport through such bridge systems and see that the transport properties are significantly affected by (a ...

The Electron Transport Chain and Carcinogenesis
2008Major metabolic changes that affect the balance between respiration and glycolysis occur during carcinogenesis. It is therefore not surprising that it has long been suggested that abnormal activity of the mitochondrial electron transfer chain could play a role in the underlying pathophysiologic process.
