  1. 1. Protection of Photosystem II from Photodamage during the Assembly of the Water Oxidizing Complex

    Författare :Maria Rova; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TyrosineD; cytochrome b559; Photoinhibition; Photoactivation; Botany; Botanik;

    Sammanfattning : Photosystem II catalyses the light driven oxidation of water, which is a key reaction in oxygenic photosynthesis. This enzyme is, however, exposed to light induced degradation, which decreases the efficiency of the photosynthetic process. LÄS MER

  2. 2. Characterization of auxiliary membrane proteins in the chloroplast of Arabidopsis thaliana

    Författare :Lotta von Sydow; Christiane Funk; Wolfgang Schröder; Thomas Pfannschmidt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Arabidopsis; chaperone; chloroplast; Cytochrome b559; FtsH; membrane proteins; photosynthesis; Photosystem II; protease; PsbY.; Arabidopsis; chaperone; Cytochrome b559; fotosyntes; fotosystem II; FtsH; kloroplast; membranprotein; proteas; PsbY.; biokemi; Biochemistry;

    Sammanfattning : In nature, sessile plants have to adapt to their environment and to the never ending changes they are exposed to. They do so mainly by proteomic and metabolomic changes. In all cells, there are complex networks of auxiliary proteins that are responsible for quality control of all the cell's proteins. LÄS MER

  3. 3. Electron Donor Systems in Natural and Artificial Photosynthesis

    Författare :Ann Magnuson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solar energy; artificial photosynthesis; Photosystem II; EPR; Biology; Biologi;

    Sammanfattning : Photosynthesis is the process by which light energy is converted into chemical products, in photoautotrophic bacteria, algae and plants. The principal idea is the production of reducing agents by photo-induced oxidation of a sacrificial electron donor. LÄS MER

  4. 4. Oxidation and reduction reactions of the water-oxidizing complex in photosystem II

    Författare :Long Vo Pham; Johannes Messinger; Imre Vass; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosystem II PSII ; oxidation; reduction; flash induced oxygen evolution pattern FIOP ; water; oxygen; global fitting program GFP ; thylakoids; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : 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. LÄS MER
