  2. 1. Exploring the Interplay of Lipids and Membrane Proteins

    Author : Candan Ariöz; Åke Wieslander; Daniel O. Daley; Malcolm East; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation; Biochemistry; biokemi;

    Abstract : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. READ MORE

  4. 2. Membrane-mimetic systems : Novel methods and results from studies of respiratory enzymes

    Author : Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; Biochemistry; biokemi;

    Abstract : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.

  5. 3. Xanthophyll Cycle in the Light of Thylakoid Membrane Lipids - Membrane Packing, Curvature Elastic Stress and Enzyme Binding

    Author : Anna Szilagyi; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; steroider; Lipids; steroids; membranes; Lipider; enzymologi; HPLC; laurdan; fluorescence spectroscopy; Proteins; enzymology; Proteiner; curvature elastic stress; enzyme binding; thylakoid membrane; membrane fluidity; lipid packing; histidine; VDE; zeaxanthin; xanthophyll cycle; mebran;

    Abstract : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. The enzyme, violaxanthin de-epoxidase (VDE) catalyses the conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin. VDE is a membrane-hosted enzyme during its activity.

  6. 4. Synthesis and protein curing abilities of membrane glycolipids

    Author : Malin Wikström; Åke Wieslander; Anthony Lee; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; membrane; lipids; glycolipids; nonbilayer-prone; Biochemistry; Biokemi;

    Abstract : There are many types of membrane lipids throughout Nature. Still little is known about synthesizing pathways and how different lipids affect the embedded membrane proteins. The most common lipids are glycolipids since they dominate plant green tissue. Glycolipids also exist in mammal cells as well as in most Gram-positive bacteria. READ MORE

  7. 5. Membrane effects on proton transfer in cytochrome c oxidase

    Author : Linda Näsvik Öjemyr; Peter Brzezinski; Anthony G. Lee; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; cytochrom c oxidase; lipids; membrane; proton transfer; Biochemistry; biokemi;

    Abstract : The biological membrane is composed of lipids and proteins that make up dynamic barriers around cells and organelles. Membrane-spanning proteins are involved in many key processes in the cell such as energy conversion, nerve conduction and signal transduction. READ MORE
