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

    Author : Candan Ariöz; Åke Wieslander; Daniel O. Daley; Malcolm East; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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. Synthesis and protein curing abilities of membrane glycolipids

    Author : Malin Wikström; Åke Wieslander; Anthony Lee; Stockholms universitet; []
    Keywords : 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

  5. 3. Protein and lipid interactions within the respiratory chain : Studies using membrane-mimetic systems

    Author : Tobias Nilsson; Peter Brzezinski; Petra Hellwig; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; ATP synthase; Bioenergetics; membrane-mimetics; Rcf1; liposomes; oxidative phosphorylation; lipids; protein-protein interactions; Biochemistry; biokemi;

    Abstract : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. READ MORE

  6. 4. Milk Membrane Lipids - Dispersions, Emulsions and Interactions with Proteins

    Author : Rianne Waninge; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Model milk membrane lipids; Emulsions; Vesicles; Cryo-TEM; Milk fat globule membrane; MFGM; Livsmedelsteknik;

    Abstract : Milk is a dilute aqueous dispersion with a complex mixture of proteins, fat, carbohydrates, vitamins and minerals. Milk membrane lipids are a part of the milk fat globule membrane (MFGM), which covers the fat globules. During dairy processing membrane material is released and surface structure features are altered. READ MORE

  7. 5. Structure and lipid interactions of membrane-associated glycosyltransferases : Cationic patches and anionic lipids regulate biomembrane binding of both GT-A and GT-B enzymes

    Author : Scarlett Szpryngiel; Lena Mäler; Marcelo Guerins; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glycosyltransferase; monotopic membrane proteins; galactolipids; NMR; chitin synthase; DGD2; LPS; WaaG; MIT domain; Biophysics; biofysik;

    Abstract : This thesis concerns work on structure and membrane interactions of enzymes involved in lipid synthesis, biomembrane and cell wall regulation and cell defense processes. These proteins, known as glycosyltransferases (GTs), are involved in the transfer of sugar moieties from nucleotide sugars to lipids or chitin polymers. READ MORE
