The lipoproteins of cyanobacterial photosystem II
Journal of Photochemistry and Photobiology B: Biology, 2011Photosystem II (PSII) complexes from cyanobacteria and plants perform water splitting and plastoquinone reduction and yet have a different complement of lumenal extrinsic proteins. Whereas PSII from all organisms has the PsbO extrinsic protein, crystal structures of PSII from cyanobacteria have PsbV and PsbU while green algae and higher plants instead ...

On the dimerization of chlorophyll in photosystem II
Physical Chemistry Chemical Physics, 2011In photosystem II, absorbed light energy is transferred to a reaction centre consisting of chlorophyll units. Release of an electron from the reaction centre is the starting point for the charge separation and electron transport chain in PSII. Crystal structures of the reaction centre have identified two chlorophyll monomers forming a dimer with a ...

Electron transfer in photosystem II
Photosynthesis Research, 1985The picture presently emerging from studies on the mechanism of photosystem II electron transport is discussed. The reactions involved in excitation trapping, charge separation and stabilization of the charge pair in the reaction center, followed by the reactions with the substrates, plastoquinone reduction and water oxidation, are described ...

Copper in photosystem II: association with LHC II
Photosynthesis Research, 1987Photosystem II particles from spinach and barley contained 2.5 and 4.2 Cu per 300 chlorophylls respectively. This Cu was resistant to removal by EDTA. A large percentage of the PSII Cu in both plants is associated with the light-harvesting chlorophyll a/b protein, LHCII; 46% in barley and 76% in spinach.

Structure of Photosystems I and II
2007Photosynthesis is the major process that converts solar energy into chemical energy on Earth. Two and a half billion years ago, the ancestors of cyanobacteria were able to use water as electron source for the photosynthetic process, thereby evolving oxygen and changing the atmosphere of our planet Earth.

Organization of Plant Photosystem II and Photosystem I Supercomplexes
2018In nature, plants are continuously exposed to varying environmental conditions. They have developed a wide range of adaptive mechanisms, which ensure their survival and maintenance of stable photosynthetic performance. Photosynthesis is delicately regulated at the level of the thylakoid membrane of chloroplasts and the regulatory mechanisms include a ...

Genetic Analysis of the Form and Function of Photosystem I and Photosystem II
Annual Review of Genetics, 1995Photosystem I (PSI) and photosystem II (PSII) are two multisubunit pigment-protein complexes in the thylakoid membranes in the chloroplasts of plants, algae, and in cyanobacteria. In recent years, directed mutagenesis has been used to specifically modify individual polypeptide components of both PSI and PSII in cyanobacteria and the green alga ...
