  1. 1. Light Protection in Plants: Characterisation of Violaxanthin de-epoxidase

    Författare :Erik Hallin; Biokemi och Strukturbiologi; []
    Nyckelord :violaxanthin de-epoxidase; cysteine; disulphide bond; function; pH activation; oligomerisation; circular dichroism; crosslinking; small angle x-ray scattering;

    Sammanfattning : Plants and algae need light to drive the photosynthetic machinery. An excess of light will, however, result in damage to the photosynthetic machinery and to the rest of the organism. The surplus of energy, when exposed to light stress is converted into less harmful heat energy through a process called non-photochemical quenching. LÄS MER

  3. 2. Protein Dynamics Studied by NMR. Kinetics of the Adipocyte Fatty Acid-Binding Protein and Oligomerisation of the Low Molecular Weight Protein Tyrosine Phosphatase

    Författare :Tomas Åkerud; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Nuclear magnetic resonance spectroscopy (NMR) has been used to determine the kinetics of ligand binding to the adipocyte fatty acid-binding protein (A-FABP), as well as the oligomerisation and inter- and intramolecular dynamics of the low molecular weight-protein tyrosine phosphatase (LMW-PTP) in solution. NMR spectroscopy is sensitive to dynamic processes on timescales ranging from picoseconds to days. LÄS MER

  4. 3. The Interaction of the Adenovirus E1B-55K Protein with a Histone Deacetylase Complex: Its Importance in Regulation of P53 Protein Functions

    Författare :Tanel Punga; Göran Akusjärvi; Klas G. Wiman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; adenovirus; E1B-55K; p53; histone acetylation; Sin3; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : The human tumour suppressor protein p53 is an effective inhibitor of cell growth, by inducing cell cycle arrest and apoptosis. However, p53-induced cell growth inhibition can be detrimental for virus multiplication. Therefore, viruses encode for proteins, which can interfere with the functions of the p53 protein. LÄS MER

  5. 4. A Tale of Chaos and Colour Influencing the photophysical properties and glass forming abilities of BODIPY dyes via structural modification

    Författare :Clara Schäfer; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BODIPYs; structure-to-optical properties relationship; entropy; amorphous materials; exciton coupling;

    Sammanfattning : Organic dyes are everyday contributors in chemistry, physics and biology. BODIPY dyes were used as model dye class in this thesis. They are well-known for their versatility, which mainly originates from the tuneability of their photophysical properties upon changes in their molecular structure. LÄS MER

  7. 5. Studies of penta-decameric binding proteins: AP-4 and CBF-A

    Författare :Alaitz Aranburu; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; transplantation; Metabolism; serologi; metabolism; Biokemi; serology; Immunology; hnRNP H; NPM; CBF-A; AP-4; transcription; B cells; immunoglobulin; Immunologi;

    Sammanfattning : Each immunoglobulin (Ig) V gene segment contains an upstream promoter region. The octamer element and the TATA box are the only elements that are conserved in all Ig promoters. The presence of the octamer element is necessary, but not sufficient to support high levels of transcription. LÄS MER
