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

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

    Abstract : 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. READ MORE

  4. 17. The role of polysaccharide modifications during Drosophila development

    Author : Florian Lüders; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ontogeni; growth animal ; embryologi; Development biology; Decapentaplegic; Hedgehog; Wingless; Sulfation; Pipe; Glycosaminoglycan; Glycosyltransferase; ontogeny; embryology; Utvecklingsbiologi;

    Abstract : Glucosides attached to proteins and lipids have been shown to modulate the activity of signal transduction pathways regulating growth and patterning processes during animal development. In particular, O-linked glycans such as glycosaminoglycans (GAGs) have been implicated in modulation of growth factor signaling pathways. READ MORE

  5. 18. The advantages of being small : Glycosyltransferases in many dimensions and glycolipid synthesis in Mycoplasma Pneumoniae

    Author : Maria Rosén Klement; Åke Wieslander; Christelle Breton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glycosyltransferase; lipid; membrane; glycolipid; ACC; PLS-DA; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The synthesis and breakdown of sugars is one of the most important functions in Nature. Consequently, sugar structures are used both as energy storage and as building blocks to stabilise and protect the cell. The formation of these structures is performed by glycosyltransferases (GT), an enzyme group structurally conserved within all kingdoms. READ MORE

  6. 19. Elucidating Genetic and Biochemical Aspects of the P1 and Sda Carbohydrate Histo-Blood Group Antigens

    Author : Linn Stenfelt; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Group; P1 antigen; Sda antigen; A4GALT; B3GALNT2; glycosyltransferase; red blood cell; transfusion medicine;

    Abstract : Human histo-blood groups are inherited polymorphic variants that occur in the molecular structures on the humanred blood cell (RBC) surface. Introducing foreign RBCs into a recipient lacking an antigen may activate the humoraldefence leading to a hemolytic transfusion reaction. READ MORE

  7. 20. Structure Elucidations of Bacterial Polysaccharides using NMR Spectroscopy and Bioinformatics

    Author : Jonas Ståhle; Göran Widmalm; Evgeny Vinogradov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Bioinformatics; NMR Spectroscopy; Lipopolysaccharide; Glycosyltransferase; Computer-Assisted Structure Elucidation; O-antigen; Biosynthesis; Organic Chemistry; organisk kemi;

    Abstract : Carbohydrates are ubiquitous components in nature involved in a range of tasks. They cover every cell and contribute both structural stability as well as identity. Lipopolysaccharides are the outermost exposed part of the bacterial cell wall and the primary target for host-pathogen recognition. READ MORE
