  2. 1. Shining light on unknown function proteins

    Author : Riccardo Diamanti; Martin Högbom; Hans-Petter Hersleth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; metalloproteins; biochemistry; metabolism; biokemi; Biochemistry;

    Abstract : The study of protein structure and function is a fundamental step for understanding biological systems and for creating a solid ground for future drug development. Despite the development of novel ground-breaking biochemical and bioinformatical tools in the last decades, most proteins found in nature still have unknown assigned function. READ MORE

  4. 2. Expression and purification of membrane proteins: Focus on the G-protein coupled receptor MC4r

    Author : Viveka Dolby; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteiner; enzymologi; Proteins; melanocortin 4 receptor; GPCR; purification; Expression; membrane proteins;

    Abstract : Membrane proteins are crucial components of the cell and are involved in many biological processes. Recombinant overexpression systems together with different purification methods are necessary to obtain large amounts of purified receptor for biophysical and functional studies. READ MORE

  5. 3. Plant Oxylipins and Lipid Transfer Proteins in Defense : - It’s all about the fat

    Author : Per Fahlberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Oxylipins, the oxygenated metabolites of polyunsaturated fatty acids (PUFAs), are found in many eukaryotic organisms. In plants, several enzymes can produce different types of oxylipins, and the chloroplast structural galactolipids mono- and digalactosyl diacylglycerol (MGDG and DGDG, respectively) are examples of sources of substrate PUFAs.

  6. 4. The Ins and Outs of Membrane Proteins : Topology Studies of Bacterial Membrane Proteins

    Author : Mikaela Rapp; Gunnar von Heijne; Christopher Tate; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane protein; topology; dual topology; Biochemistry; Biokemi;

    Abstract : α-helical membrane proteins comprise about a quarter of all proteins in a cell and carry out a wide variety of essential cellular functions. This thesis is focused on topology analyses of bacterial membrane proteins. The topology describes the two-dimensional structural arrangement of a protein relative to the membrane. READ MORE

  7. 5. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

    Author : Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

    Abstract : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. READ MORE
