  3. 32. Beyond Classical Ruthenium(II) Polypyridyl Complexes : Photosensitizers as Building Blocks For Linear Donor-Photosensitizer-Acceptor Assemblies

    Författare :Michael Jäger; Olof Johansson; Edwin Constable; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Sammanfattning : This thesis describes ruthenium(II) polypyridyl-type complexes tailored for artificial photosynthesis. Inspired by Nature, the primary events in photosystem II are mimicked by donor-photosensitizer-acceptor (D-P-A) assemblies. LÄS MER

  4. 33. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II

    Författare :Sindra Peterson Årsköld; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; S2 state; second cycle; Biochemistry; Metabolism; Biokemi; metabolism; S0 state; light-adaptation; pulsed EPR; methanol; relaxation; microwave power saturation; S-cycle; Oxygen-evolving complex; Water-oxidizing complex;

    Sammanfattning : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). LÄS MER

  5. 34. On the molecular mechanism of LHCII proteolysis during photoacclimation of photosystem II

    Författare :Dan-Hui Yang; Peter Horton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : Higher plants and green algae have a remarkable ability to respond to fluctuations in the light intensity. Plants adapted to low or high light regimes possess larger or smaller light-harvesting antennae respectively. LÄS MER

  7. 35. 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
