Magnetization switching on such a time scale has potential to be a significant boost for the data storage industry. LÄS MER

  5. 10. Water and Protein Dynamics in Biological Systems Studied by Magnetic Relaxation Dispersion

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Persson Sunde; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein dynamics; ubiquitin; BPTI; Escherichia coli; Haloarcula marismortui; nuclear magnetic resonance; protein hydration; magnetic relaxation dispersion; water dynamics; cell water;

    Sammanfattning : The results presented in this thesis demonstrate that the magnetic relaxation dispersion (MRD) technique can provide information of relevance to protein biophysics, magnetic resonance imaging and cell biology. By immobilizing proteins with covalent cross-links, intermittent protein dynamics on the previously inaccessible ns-µs time scale could be probed with MRD via the exchange of water molecules between internal cavities and the surrounding bulk solvent phase.
