  1. 1. Functional dynamics of glycosyltransferases : Solution-state NMR studies of peripheral membrane proteins involved in glycolipid biosynthesis in bacteria

    Författare :Joan Patrick; Lena Mäler; Magnus Wolf-Watz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik;

    Sammanfattning : Antibiotic resistance is an existential threat enabled by bacterial adaptation and fuelled by inappropriate use of medication. The ensuing shortage of effective treatments has led to a rise in deaths linked to resistant bacterial pathogens. LÄS MER

  3. 2. Membrane interactions of glycosyltransferases

    Författare :Jobst Liebau; Lena Mäler; Christofer Lendel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipid; bicelle; glycosyltransferase; NMR; Biophysics; biofysik;

    Sammanfattning : Many important biological processes occur near or in membranes. The role of membranes is not merely confined to compartmentalization, they also form the matrix for membrane associated proteins and are of functional importance. Membrane associated proteins on the other hand require specific membrane properties for proper function. LÄS MER

  4. 3. Glycosaminoglycan Biosynthesis in Zebrafish

    Författare :Beata Filipek-Górniok; Lena Kjellén; Johan Ledin; Kay Grobe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparan sulfate; chondroitin dermatan sulfate; biosynthesis; development; N-deacetylase N-sulfotransferase; glycosyltransferases; morpholino; CRISPR-Cas9;

    Sammanfattning : Proteoglycans (PGs) are composed of highly sulfated glycosaminoglycans chains (GAGs) attached to specific core proteins. They are present in extracellular matrices, on the cell surface and in storage granules of hematopoietic cells. LÄS MER

  5. 4. Computer-Assisted Carbohydrate Structural Studies and Drug Discovery

    Författare :Magnus Lundborg; Göran Widmalm; Hans-Christian Siebert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; molecular docking; molecular dynamics simulation; fragment-based virtual screening; NMR spectroscopy; computer-aided drug design; computer-aided structure elucidation; glycosyltransferases; Escherichia coli; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Carbohydrates are abundant in nature and have functions ranging from energy storage to acting as structural components. Analysis of carbohydrate structures is important and can be used for, for instance, clinical diagnosis of diseases as well as in bacterial studies. The complexity of glycans makes it difficult to determine their structures. LÄS MER

  7. 5. Analysis of Binding Events and Diffusion in Living Cells

    Författare :Markus Elsner; Göteborgs universitet; []
    Nyckelord :COPI; Golgi; Diffusion; Glycosyltransferases; Sorting; Molecular; Crowding;

    Sammanfattning : It is well known that diffusion is the main mode of transport in living cells, but the consequences of diffusion in a complex cellular environment are not generally appreciated. In this thesis, we have investigated several aspects of how diffusion properties influence the observability of cellular binding kinetics and how they can be used to obtain information about the environment of proteins and other molecules.
