  1. 1. Molecular principles of protein stability and protein-protein interactions

    University dissertation from Stockholm : KTH

    Author : Christofer Lendel; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; binding thermodynamics; induced fit; molten globule; NMR spectroscopy; protein engineering; protein-protein interactions; protein stability; protein structure.; TECHNOLOGY Bioengineering Structural biochemistry; TEKNIKVETENSKAP Bioteknik Strukturbiokemi;

    Abstract : Proteins with highly specific binding properties constitute the basis for many important applications in biotechnology and medicine. Immunoglobulins have so far been the obvious choice but recent advances in protein engineering have provided several novel constructs that indeed challenge antibodies. READ MORE

  2. 2. Protein-water interactions studied by molecular dynamics simulations

    University dissertation from Department of Chemistry, Lund University

    Author : Filip Persson; Lund University.; Lunds universitet.; [2018-02-14]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MD simulations; NMR nuclear magnetic resonance ; MRD; water dynamics; protein dynamics; protein hydration; Amide hydrogen exchange; Internal water; compressibility;

    Abstract : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. READ MORE

  3. 3. NMR Studies of Bacterial Albumin-Binding Modules

    University dissertation from Eva Hagen/Bodil Forsvik, Biophysical Chemistry, Lund University

    Author : Maria U Johansson; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi; Physical chemistry; three-helix bundle; protein structure; protein PAB; protein-protein interactions; protein G; protein dynamics; NMR; module shuffling; GA module; evolution; albumin-binding; bacterial surface proteins;

    Abstract : Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. READ MORE

  4. 4. NMR studies of protein dynamics and structure

    University dissertation from Umeå : Umeå universitet. Kemiska institutionen

    Author : Jörgen Ådén; Umeå universitet.; [2010]

    Abstract : Enzymes are extraordinary molecules that can accelerate chemical reactions by several orders of magnitude. With recent advancements in structural biology together with classical enzymology the mechanism of many enzymes has become understood at the molecular level. READ MORE

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

    University dissertation from Umeå : Umeå universitet. Kemiska institutionen

    Author : Erik Persson Sunde; Lund University.; Lunds universitet.; [2009]
    Keywords : 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;

    Abstract : 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.
