Oxygen is a natural acceptor of electrons in the respiratory pathway of aerobic organisms
and in many other biochemical reactions. Aerobic metabolism is always associated with the …

Isoprenoid quinones are one of the most important groups of compounds occurring in
membranes of living organisms. These compounds are composed of a hydrophilic head …

Our current understanding of the PSII reaction centre owes a great deal to comparisons to
the simpler and better understood, purple bacterial reaction centre. Here we provide an …

Photosysthetic cleavage of water molecules to molecular oxygen is a crucial process for all
aerobic life on the Earth. Light-driven oxidation of water occurs in photosystem II (PSII)—a …

The energy-converting redox enzymes perform productive reactions efficiently despite the
involvement of high energy intermediates in their catalytic cycles. This is achieved by kinetic …

▪ Abstract Chlororespiration has been defined as a respiratory electron transport chain (ETC)
in interaction with the photosynthetic ETC in thylakoid membranes of chloroplasts. The …

The photosystem II core complex is the water: plastoquinone oxidoreductase of oxygenic
photosynthesis situated in the thylakoid membrane of cyanobacteria, algae and plants. It …

In this study, we performed an integrated physiological and chloroplast proteome analysis of
wheat seedling leaves under salt and osmotic stresses by label-free based quantitative …

Inactivation of a plastid located quinone–oxygen oxidoreductase gene in the immutans
Arabidopsis mutant leads to a photobleached phenotype because of a lack of …

The photogeneration of hydroxyl radicals (OH•) in photosystem II (PSII) membranes was
studied using EPR spin-trapping spectroscopy. Two kinetically distinguishable phases in the …
