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

    University dissertation from Stockholm : Stockholm University

    Author : Said Eshaghi; Stockholms universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  4. 4. Studies of the two redox active tyrosines in Photosystem II

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nigar Ahmadova; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photosystem II; Tyrosine Z and D; proton-coupled electron transfer;

    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. 5. EPR Studies of Photosystem II Characterizing Water Oxidizing Intermediates at Cryogenic Temperatures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kajsa G.V. Havelius; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi;

    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
