  1. 1. Essential conserved active site residues in class Ia ribonucleotide reductase from Escherichia coli : identification of radical reaction intermediates and radical transfer intermediates

    Författare :Annika Persson; Marc Fontecave; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular Biology; molekylärbiologi;

    Sammanfattning : The enzyme ribonucleotide reductase catalyzes the reduction of ribonucleotides to the corresponding deoxyribonucleotides, the building blocks of DNA. The class Ia enzyme from Escherichia coli consists of two homodimeric subunits denoted protein R1 and protein R2, each inactive alone. LÄS MER

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

    Författare :Kajsa G.V. Havelius; Stenbjörn Styring; Holger Dau; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    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
