  1. 11. Taming the Griffin : Membrane interactions of peripheral and monotopic glycosyltransferases and dynamics of bacterial and plant lipids in bicelles

    Författare :Jobst Liebau; Lena Mäler; Charles Sanders; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane; bicelle; lipid; detergent; lipopolysaccharide; glycosyltransferase; WaaG; fluorescence; circular dichroism; NMR; paramagnetic relaxation enhancement; model-free approach; dynamics; Biophysics; biofysik;

    Sammanfattning : Biological membranes form a protective barrier around cells and cellular compartments. A broad range of biochemical processes occur in or at membranes demonstrating that they are not only of structural but also of functional importance. One important class of membrane proteins are membrane-associated glycosyltransferases. LÄS MER

  3. 12. Membrane Fluidity Regulation: From C. elegans to mammalian cells

    Författare :Ranjan Devkota; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAQR-2; adiponectin receptors; IGLR-2; saturated fats; membrane fluidity; fatty acid desaturation; unsaturated fatty acid; membrane homeostasis;

    Sammanfattning : Biological membranes are primarily an assembly of lipids and proteins. Collectively, these constituents within a phospholipid bilayer determine the physical membrane properties such as fluidity, viscosity, thickness, packing and permeability. Maintenance of membrane properties within acceptable margins, i.e. LÄS MER

  4. 13. Apoptosis Regulation via the Mitochondrial Pathway : Membrane Response upon Apoptotic Stimuli

    Författare :Marc-Antoine Sani; Gerhard Grobner; Antoinette Killian; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apoptosis; BH4 peptide; Bax-α1 peptide; model membrane; cardiolipin; solid phase peptide synthesis; circular dichroism; solid-state nuclear magnetic resonance spectroscopy.; Biophysics; Biofysik;

    Sammanfattning : The aim of this thesis was the investigation of the mitochondrial response mechanisms upon apoptotic stimuli. The specific objectives were the biophysical characterization of membrane dynamics and the specific roles of lipids in the context of apoptotic regulation occurring at the mitochondrion and its complex membrane systems.

  5. 14. The molecular basis for substrate recognition and gating in sugar transporters

    Författare :Sarah McComas; David Drew; Philip Biggin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane transport; sugar transporter; simulations; lipids; antimalarial drugs; biokemi; Biochemistry;

    Sammanfattning : Sugar is a vital sustenance for most forms of life. For a cell to take up sugar, specialized transport proteins embedded into the membrane bilayer known as sugar porters, are required. LÄS MER

  7. 15. Diet and Cardiometabolic Disease : Dietary trends and the impact of diet on diabetes and cardiovascular disease

    Författare :Benno Krachler; Bernt Lindahl; Göran Hallmans; Mats Eliasson; Ingvar Bosaeus; Umeå universitet; []

    Sammanfattning : Cardiovascular diseases are the leading cause of death in most industrialised countries and in developing countries the trend in cardiovascular-related deaths is increasing. World-wide, type 2 diabetes mellitus (T2DM) is an emerging cause of disability and premature death. LÄS MER
