High-resolution dissection of photosystem II electron transport reveals differential response to water deficit and heat stress in isolation and combination in pearl millet [Pennisetum glaucum (L.) R. Br.]

Frontiers in Plant Science, 2022
Heat and Water Deficit Stress (WDS) tend to impede and restrict the efficiency of photosynthesis, chlorophyll fluorescence, and maximum photochemical quantum yield in plants based on their characteristic ability to interfere with the electron transport ...

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 ...

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.

Inhibition of electron transport at the cytochrome b₆f complex protects photosystem II from photoinhibition [PDF]

FEBS Letters, 2000
Photoinhibition of photosystem II (PS II) activity was studied in thylakoid membranes illuminated in the presence of the inhibitor of the cytochrome b6f complex 2′iodo‐6‐isopropyl‐3‐methyl‐2′,4,4′‐trinitrodiphenylether (DNP‐INT). DNP‐INT was found to decrease photoinhibition.

Conducting chiral nickel(ii) bis(dithiolene) complexes: structural and electron transport modulation with the charge and the number of stereogenic centres [PDF]

Journal of Materials Chemistry C, 2021
Chiral nickel(ii) bis(dithiolene) complexes based on the mono- and bis-methylated ligands me-dddt and dm-dddt are Mott insulators or band gap semiconductors, with their conductivity modulated by the counter-ion and the number of stereogenic centres.

Effect of Ganoderma lucidum on the activities of mitochondrial dehydrogenases and complex I and II of electron transport chain in the brain of aged rats

Experimental Gerontology, 2008
Dysfunction of the mitochondrial respiratory chain, being direct intracellular source of reactive oxygen species (ROS), is important in the pathogenesis of number of ageing associated human disorders. Effect of ethanol extract of Ganoderma lucidum on the activities of mitochondrial dehydrogenases; complex I and II of electron transport chain have been ...

Complex II subunit SDHD is critical for cell growth and metabolism, which can be partially restored with a synthetic ubiquinone analog

BMC Molecular and Cell Biology, 2021
Background Succinate dehydrogenase (Complex II) plays a dual role in respiration by catalyzing the oxidation of succinate to fumarate in the mitochondrial Krebs cycle and transferring electrons from succinate to ubiquinone in the mitochondrial electron ...

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.
