Dynamic water bridging and proton transfer at a surface carboxylate cluster of photosystem II [PDF]
, 2019 Proton-transfer proteins are often exposed to the bulk clusters of carboxylate groups that might bind protons transiently. This raises important questions as to how the carboxylate groups of a protonated cluster interact with each other and with water ...

Proton-mediated photoprotection mechanism in photosystem II
Frontiers in Plant Science, 2022 Photo-induced charge separation, which is terminated by electron transfer from the primary quinone QA to the secondary quinone QB, provides the driving force for O2 evolution in photosystem II (PSII).

The response of sunflower to acute disturbance in water availability
Acta Agriculturae Slovenica, 2005 The influence of disturbance in water availability to electron flow in photosystem II was studied in five cultivars of sunflower. The results showed unaffected optimal quantum yield of photosystem II in the plants exposed to limited water supply ...

Oxidized amino acid residues in the vicinity of Q(A) and Pheo(D1) of the photosystem II reaction center: putative generation sites of reducing-side reactive oxygen species. [PDF]
PLoS ONE, 2013 Under a variety of stress conditions, Photosystem II produces reactive oxygen species on both the reducing and oxidizing sides of the photosystem. A number of different sites including the Mn4O5Ca cluster, P680, PheoD1, QA, QB and cytochrome b559 have ...

Water oxidation in photosystem II [PDF]
Photosynthesis Research, 2019 Biological water oxidation, performed by a single enzyme, photosystem II, is a central research topic not only in understanding the photosynthetic apparatus but also for the development of water splitting catalysts for technological applications.
