Erratum to: Connectivity between electron transport complexes and modulation of photosystem II activity in chloroplasts [PDF]

Photosynthesis Research, 2017
In chloroplasts, photosynthetic electron transport complexes interact with each other via the mobile electron carriers (plastoquinone and plastocyanin) which are in surplus amounts with respect to photosystem I and photosystem II (PSI and PSII), and the cytochrome b 6 f complex.

Complex effects of pH on ROS from mitochondrial complex II driven complex I reverse electron transport challenge its role in tissue reperfusion injury [PDF]

, 2020
ABSTRACTGeneration of mitochondrial reactive oxygen species (ROS) is an important process in triggering cellular necrosis and tissue infarction during ischemia-reperfusion (IR) injury. Ischemia results in accumulation of the metabolite succinate. Rapid oxidation of this succinate by mitochondrial complex II (Cx-II) during reperfusion reduces the co ...

NEK7 couples SDHB to orchestrate respiratory chain electron transport homeostasis that impedes liver fibrosis [PDF]

Nature Communications
The mode of electron transport in mitochondrial respiratory chain determines whether it generates energy or more reactive oxygen species (ROS), a key for cellular adaptation to diverse oxygen environments.

The resistance of electron-transport chain Fe–S clusters to oxidative damage during the reaction of peroxynitrite with mitochondrial complex II and rat-heart pericardium [PDF]

Nitric Oxide, 2008
The effects of peroxynitrite and nitric oxide on the iron-sulfur clusters in complex II (succinate dehydrogenase) isolated from bovine heart have been studied primarily by EPR spectroscopy and no measurable damage to the constitutive 2Fe-2S, 3Fe-4S, or 4Fe-4S clusters was observed.

The shuttle mechanism of the electron transport by the ruthenium(II) bipyridyl complex-modified bovine adrenodoxin in the steroid hydroxylase

, 2005
Das Hauptziel der vorliegenden Arbeit war, mittels einer Photoreduktion des Adrenodoxins zu zeigen, dass das Eisen-Schwefel-Protein ohne Adrenodoxinreduktase reduziert und damit das Shuttle-Modell für Adrenodoxin überprüft werden kann. Um dieses Hauptziel zu erreichen, wurde eine verkürzte Form des Adrenodoxins, Adx(1-108), mit dem Ru(bpy)2(mbpy ...

Siccanin Is a Dual-Target Inhibitor of Plasmodium falciparum Mitochondrial Complex II and Complex III

Pharmaceuticals, 2022
Plasmodium falciparum contains several mitochondrial electron transport chain (ETC) dehydrogenases shuttling electrons from the respective substrates to the ubiquinone pool, from which electrons are consecutively transferred to complex III, complex IV ...
