1. Oxidation and reduction reactions of the water-oxidizing complex in photosystem II
Abstract : The oxygen that we breathe and food that we eat are products of the natural photosynthesis. Molecular oxygen is crucial for life on Earth owing to its role in the glycolysis and citric acid pathways that yield in aerobic organisms the energy-rich ATP molecules. READ MORE

2. EPR Studies of Photosystem II : Characterizing Water Oxidizing Intermediates at Cryogenic Temperatures
Abstract : The principles of natures own light-driven water splitting catalyst, Photosystem II (PSII), can in the future inspire us to use water as electron and proton source to generate light-driven H2 production. To mimic this challenging step, it is important to understand how the enzyme system can oxidize water. READ MORE

3. Physiological adaptations in two ecotypes of Fucus vesiculosus and in Fucus radicans with focus on salinity
Abstract : The in origin intertidal marine brown alga Fucus vesiculosus L. grow permanently sublittoral in the brackish Bothnian Sea, side by side with the recently discovered F. radicans L. Bergström et L. READ MORE

4. Studies of the two redox active tyrosines in Photosystem II
Abstract : Photosystem II is a unique enzyme which catalyzes light induced water oxidation. This process is driven by highly oxidizing ensemble of four Chl molecules, PD1, PD2, ChlD1 and ChlD2 called, P680. Excitation of one of the Chls in P680 leads to the primary charge separation, P680+Pheo-. READ MORE

5. Substrate water binding to the oxygen-evolving complex in photosystem II
Abstract : Oxygenic photosynthesis in plants, algae and cyanobacteria converts sunlight into chemical energy. In this process electrons are transferred from water molecules to CO2 leading to the assembly of carbohydrates, the building blocks of life. READ MORE
