  1. 1. Protein Folding, Binding and Evolution : PDZ domains and paralemmins as model systems

    Författare :Greta Hultqvist; Per Jemth; Ruth Nussinov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein folding; evolution; binding; allostery; Paralemmin; PDZ domain;

    Sammanfattning : Proteins present at the synapse need to be multitasking in order to perform all vital functions in this limited space. In this thesis I have analyzed the function and evolution of such proteins, focusing on the PDZ domain and the paralemmin family. The PDZ domains bind to a wide variety of interaction partners.

  2. 2. Site-Specific Recombination : Integrases, Accessory Factors and DNA Targets of P2-like Coliphages

    Författare :Lina Sylwan; Elisabeth Haggård-Ljungquist; Margaret C. M. Smith; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The temperate coliphage P2 and its family members integrate their genomes into the host Escherichia coli chromosome by a site-specific recombination mechanism to form lysogeny. Integration takes place between the complex phage attP site and the simple bacterial attB site and is catalyzed by the phage encoded integrase (Int). LÄS MER

  3. 3. Visualization of Peripheral Pain Generating Processes and Inflammation in Musculoskeletal Tissue using [11C]-D-deprenyl PET

    Författare :Mikko Aarnio; Torsten Gordh; Jens Sörensen; Magnus Peterson; Lars Ståhle; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ankle injuries; arthritis; binding site; binding target; carbon-11; deprenyl; high-throughput screening; inflammation; monoamine oxi-dase; pain; PET; whiplash; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : An objective visualization and quantification of pain-generating processes in the periphery would alter pain diagnosis and represent an important paradigm shift in pain research. Positron emission tomography (PET) radioligand [11C]-D-deprenyl has shown an elevated uptake in painful inflammatory arthritis and whiplash-associated disorder. LÄS MER

  4. 4. C4b-binding protein: Identification of binding sites and a possible function of the interaction with protein S

    Författare :Joanna Webb; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical chemistry; apoptosis; binding sites; complement; C4b-binding protein; protein S; Klinisk kemi;

    Sammanfattning : The subject of this thesis is plasma protein C4b-binding protein (C4BP). C4BP is an important regulator of the classical pathway of the complement system, a cascade-like system comprised of over 35 proteins, which partakes in the defence against micro-organisms and is involved of clearance of immune-complexes and apoptotic cells.

  5. 5. Protein Interactions: Electrostatics and Ligand Binding

    Författare :Ingemar André; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; Molekylär biofysik; secondary structure formation; protein GB1; pKa values; pH stability; NMR; electrostatic interactions; M proteins; calbindin D9k; calcium binding; cooperativity; calmodulin; calbindin D28k;

    Sammanfattning : This thesis deals with Ca2+ binding to proteins, electrostatic interactions in and between proteins as well as inter- and intramolecular interactions. A computer program was developed to determine Ca2+ binding constants from experimental titration data of proteins. LÄS MER
