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

    Författare :Kajsa G.V. Havelius; Stenbjörn Styring; Holger Dau; Uppsala universitet; []

    Sammanfattning : 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. LÄS MER
