  1. 1. Photosystem II : organization, function and regulation

    Författare :Said Eshaghi; Matthias Rögner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Sammanfattning : What makes plants, green algae and cyanobacteria so remarkable is their ability to convert light energy to chemical energy and at the same time evolve oxygen. In order to do so, they have developed a complex molecular machinery involving pigment and co-factor binding multi-protein complexes. LÄS MER

  5. 4. Regulation of electron donation to photosystem 1

    Författare :Daniel Farkas; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPR; NMR; photosystem 1; plastocyanin; protein-protein interaction; PsaF;

    Sammanfattning : Photosynthesis is the process where energy from light is used to catalyze the formation of energy-rich molecules such as NADPH and ATP. These reactions are in fact the result of a long series of electron-transfer reactions where water molecules are the source of electrons and NADP+ is the terminal electron acceptor. LÄS MER

  7. 5. Challenges in Enzyme Catalysis - Photosystem II and Orotidine Decarboxylase : A Density Functional Theory Treatment

    Författare :Marcus Lundberg; Margareta Blomberg; Per Siegbahn; Jeremy Harvey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photosystem II; oxyl radical; manganese systems; orotidine decarboxylase; reaction mechanism; density functional theory; Quantum chemistry; Kvantkemi;

    Sammanfattning : Possibly the most fascinating biochemical mechanism remaining to be solved is the formation of oxygen from water in photosystem II. This is a critical part of the photosynthetic reaction that makes solar energy accessible to living organisms. LÄS MER
