  2. 1. Regulators of Membrane Fluidity

    Author : Kiran Busayavalasa; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAQR; LRIG; membrane fluidity;

    Abstract : Caenorhabditis elegans PAQR-2 (a homolog of the mammalian AdipoR1 and AdipoR2 proteins) and IGLR-2 (homolog of the mammalian LRIG proteins) form a complex at the plasma membrane that regulates fatty acid desaturation to protect against saturated fatty acid-induced membrane rigidification. Maintenance of membrane homeostasis is fundamental for most cellular processes and, given its importance, robust regulatory mechanisms must exist that adjust lipid composition to compensate for dietary variation.

  4. 2. One key to two doors : Dual targeting peptides and membrane mimetics

    Author : Weihua Ye; Lena Mäler; Göran Kalsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : Dual targeting peptides; protein import; mitochondria and chloroplasts; bicelles; galactolipids; NMR spectroscopy; Biophysics; biofysik;

    Abstract : A targeting peptide at the N-terminus of a precursor protein usually directs the protein synthesized in the cytosol to a specific organelle in the cell. Interestingly, some targeting peptides, so-called dual targeting peptides (dTPs) can target their protein to both mitochondria and chloroplasts. READ MORE

  5. 3. 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

  6. 4. Fatty Acyl Reductases and Fatty Acyl Desaturases. Deciphering the biosynthesis of species-specific moth female sex pheromones from common fatty acids

    Author : Åsa Hagström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Moth; pheromone; insect; evolution; fatty acyl desaturase; fatty acyl reductase; endoplasmic reticulum; fatty acid biosynthesis; GFP; heterologous expression; phylogeny; cell factory; lepidoptera;

    Abstract : Moths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland.

  7. 5. Structural and Functional Studies of Membrane Proteins : From Characterisation of a Fatty Acyl-CoA Synthetase to the Discovery of Superoxide Oxidase

    Author : Camilla A. K. Lundgren; Martin Högbom; James Imlay; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Abstract : This thesis is divided into three parts; the first part describes a method for efficient screening of membrane proteins for crystallography. By utilising the properties of a folding reporter GFP it is possible to quickly and accurately screen the stability of a protein in a range of conditions without full purification. READ MORE
