The Electron Transport Chain of Rhizobium trifolii
European Journal of Biochemistry, 1980The presence of a branched respiratory chain in Rhizobium trifolii grown in batch culture on a defined medium was demonstrated. The branches of the respiratory chain difer in sensitivity to inhibition by cyanide and in affinity for oxygen. The branching point is localized at cytochrome b‐555. Electron flow from cytochrome b‐555 via cytochrome c‐549 and

The electron transport chain of Bacterionema matruchotii
Canadian Journal of Microbiology, 1981The membrane fraction of Bacterionema matruchotii contains an electron transport chain with oxidizing activity for NADH and succinate. Respiration was inhibited by KCN, 2-heptyl-4-hydroxyquinoline-N-oxide, UV light irradiation and CO. UV light irradiation, analysis of membrane extracts, and reconstitution of respiration in UV light treated membranes ...

THE SUPEROXIDE ANION AS ELECTRON DONOR TO THE MITOCHONDRIAL ELECTRON TRANSPORT CHAIN
Photochemistry and Photobiology, 1977Abstract— In isolated respiratory multienzyme complexes of beef heart mitochondria the b‐type cytochromes can be photoreduced in presence of flavin via the superoxide anion. O‐2 does not reduce cytochrome c1. In an anaerobic system, FMNH2 formed by irradiation with blue light in presence of EDTA reduces cytochromes b and c1 The possible implication of ...

The Electron-Transport Chain in Mitochondria
1987The electron-transport chain in plant mitochondria has not been studied as extensively as that in animals. Therefore, although the following account will deal primarily with plants, much of the background is derived from the research on animal mitochondria.

Electronic information transfer in a transport chain
Industrial Management & Data Systems, 2009PurposeThe purpose of this paper is to assess electronic information transfer in logistics organizations. The paper approaches information transfer as an elemental component of contemporary business to business (B2B) processes.Design/methodology/approachThe empirical material concerns companies that together comprise a logistical chain.

Kinetic modeling of the photosynthetic electron transport chain
Bioelectrochemistry, 2001A simulation model of the photosynthetic electron transport chain operating under steady state conditions is presented. The model enables the calculation of (1) the rates of electron transport and transmembrane proton translocation, (2) the proton/electron stoichiometry, (3) the number of electrons stored in the different redox centers and (4) the ...

Electron Transport in a π-Stacking Molecular Chain
The Journal of Physical Chemistry B, 2008We have investigated the electronic structure and transport properties of a pi-stacking molecular chain which is covalently bonded to a H/Si(100) surface, using the first-principles density functional theory approach combined with Green's function method.

A cytochrome b5 electron transport chain in Tetrahymena
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1983Tetrahymena microsomes contain cytochrome b5 and an NADH-dependent cytochrome b5 reductase, but these proteins are present at only one-tenth the levels observed in rat liver microsomes. We show that both proteins can be partially purified by techniques developed for the rat liver proteins.

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 ...

Effects of oxygen on the electron transport chain of photosynthesis
Planta, 1968Oxygen was taken up by both intact and broken chloroplasts when catalase was posioned. In confirmation of other work we found that oxygen enters the electron transport chain of isolated chloroplasts by oxidizing the primary photoreductant of system I.
