  1. 1. Membrane Induced Structure in Transmembrane Signaling Proteins and Peptides : Peptide–Lipid Interactions Studied by Spectroscopic Methods

    Författare :Sofia E. Unnerståle; Lena Mäler; Jason Schnell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptide-lipid interaction; paddle domain; voltage gating; voltage sensor domain; micelle; phospholipid bicelle; solution structure; HAMP domain; nuclear magnetic resonance spectroscopy; circular dichroism spectroscopy; nonspecific interaction; Biophysics; biofysik;

    Sammanfattning : Biological membranes, defining the boundary of cells and eukaryotic organelles, are mainly composed of lipids and membrane proteins. Interactions between these lipids and proteins are needed to preserve the tight seal of the membrane, but also to induce structure for proper function in many membrane proteins. LÄS MER

  3. 2. Rates and patterns of genome evolution in Lepidoptera

    Författare :Karin Näsvall; Niclas Backström; Simon Martin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromosomal rearrangements; karyotype evolution; recombination rate; Lepidoptera; genome structure; molecular evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : The evolutionary consequences of genome restructuring and chromosomal rearrangements can be significant, but the underlying mechanisms are poorly understood. This thesis explores the relationships between genome restructuring, recombination, and maintenance of genetic diversity in different butterfly species. LÄS MER

  4. 3. Unveiling biomacromolecule interactions-NMR and optical spectroscopy studies on ligand binding to DNA and lysozyme

    Författare :Lisha Wu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ruthenium compounds; intercalation; Hoechst 33258; CD; fluorescence; DNA; structure rearrangements.; lysozyme; NMR;

    Sammanfattning : Studies on intercalation of bulky binuclear ruthenium compounds into DNA have attracted attention due to their slow dissociation rate and sequence selectivity. Previous results showed that dumb-bell shaped molecules of the type [μ-(bidppz)(L)4Ru2]4+, L=phenanthroline or bipyridine, bind rapidly on the surface of DNA prior to intercalation. LÄS MER

  5. 4. Evolution and structure of leukotriene A4 hydrolase

    Författare :Filippa Kull; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Leukotriene (LT) B4 is a potent leukocyte chemotactic and aggregating agent involved in a variety of inflammatory and allergic disorders. The enzyme leukotriene A4 hydrolase catalyzes the hydrolysis of LTA4 into this proinflammatory mediator, leukotriene B4. LÄS MER

  7. 5. Structure and mechanism on the C9H9+ and C9H9- potential energy surfaces : charge control of degenerate rearrangements and homoaromatic delocalization studied by multiple labelling with 13C and 2H, 13C NMR methods and ab initio MO calculations

    Författare :Göran Jonsäll; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;
