  1. 11. The choreography of protein vibrations : Improved methods of observing and simulating the infrared absorption of proteins

    Author : Eeva-Liisa Karjalainen; Andreas Barth; Astrid Gräslund; Timothy A. Keiderling; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infrared spectroscopy; FTIR; protein; atpase; amyloid; caged compound; amide I; transition dipole coupling; exciton theory; simulation; Molecular biophysics; Molekylär biofysik; Biophysics; biofysik;

    Abstract : The work presented in this thesis has striven toward improving the capability to study proteins using infrared (IR) spectroscopy. This includes development of new and improved experimental and theoretical methods to selectively observe and simulate protein vibrations. READ MORE

  2. 12. Hydrophobicity Patterns in Protein Folding

    Author : Frank Potthast; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; global optimization; multisequence; Fourier analysis; hydrophobicity; protein folding; simulated tempering; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; gravitation; relativitet; termodynamik; statistisk fysik; alpha-helix; protein design.; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; relativity; Fysicumarkivet A:1998:Potthast;

    Abstract : The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. READ MORE

  3. 13. Biocomputational studies on protein structures

    Author : Erik Nordling; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Biology in the post-genomic era produces large amount of data. This, in combination with the need for efficient algorithms to find genes in the genomic material, has brought a renaissance into the field of computational biology. READ MORE

  4. 14. Prediction, Design and Determination of Protein Structures

    Author : Sebastian Rämisch; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein design; Rosetta; Fold-and-Dock; leucine rich repeat proteins; coiled-coils; molecular replacement; ab initio phasing; temperature stability; fluorescent proteins;

    Abstract : The three-dimensional structure of protein is encoded in its amino acid sequence. Modern structure prediction algorithms make it possible to predict the structure of small proteins using sequence information alone. READ MORE

  5. 15. Biophysical characterization of protein-protein interactions involving intrinsically disordered proteins

    Author : Ida Nyqvist; Jakob Dogan; Ivarsson Ylva; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Protein-protein interactions; Disorder-to-order transition; Rate-limiting transition state; Ф-value analysis; NMR relaxation; Side-chain dynamics; Backbone dynamics; Conformational entropy change; Biophysics; biofysik;

    Abstract : Intrinsically disordered proteins and regions (IDPs/Rs) are proteins that do not form stable and well-defined structures in their free states but rather occupy an ensemble of conformations that change over time while still staying functional. They are prevalent in the eukaryotic proteome and are involved in various vital processes in the cell where they often interact with their binding partners through coupled binding and folding reactions.
