  1. 1. Holographic Wilson Loops : Quantum String Corrections

    Författare :Daniel Ricardo Medina Rincon; Konstantin Zarembo; Gianluca Grignani​; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Gauge-string correspondence; AdS CFT; Wilson loops; String theory; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The gauge-string duality has been one of the most exciting areas in theoretical physics as it connects strongly coupled field theories with weakly interacting strings. The present thesis concerns the study of Wilson loops in this correspondence. LÄS MER

  2. 2. Dynamics of peptide chains during co-translational translocation, membrane integration & domain folding

    Författare :Rickard Hedman; Gunnar von Heijne; Daniel N. Wilson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ribosome; membrane integration; translocation; folding; arrest peptide; SecM; Biochemistry; biokemi;

    Sammanfattning : The biosynthesis of proteins occurs at the ribosomes, where amino acids are linked together into linear chains. Nascent protein chains may undergo several different processes during their synthesis. Some proteins begin to fold, while others interact with chaperones, targeting factors or processing enzymes.

  3. 3. Characterizing Elongation of Protein Synthesis and Fusidic Acid Resistance in Bacteria

    Författare :Srihari Nagendra Ravi Kiran Koripella; Suparna Sanyal; Daniel Wilson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Elongation factor-G; FusB; GTP; Staphylococcus aureus; Escherichia coli and Fusidic acid; Molecular Biology; Molekylärbiologi;

    Sammanfattning : Protein synthesis is a highly complex process executed by the ribosome in coordination with mRNA, tRNAs and translational protein factors. Several antibiotics are known to inhibit bacterial protein synthesis by either targeting the ribosome or the proteins factors involved in translation. LÄS MER

  4. 4. Structural characterisation of mitochondrial macromolecular complexes using cryo-EM : Mitoribosome biogenesis and respiratory chain supercomplex

    Författare :Sorbhi Rathore; Martin Ott; Daniel Wilson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; mitoribosome biogenesis; mitoribosome assembly factors; yeast respiratory supercomplexes; single particle electron cryo-microscopy; cryo-EM sample preparation; Biochemistry; biokemi;

    Sammanfattning : Mitochondria, popularly known as powerhouse of the cell, contain specialised mitoribosomes that synthesise essential membrane proteins. These essential proteins are required to form enzyme complexes, which carry out the process of oxidative phosphorylation (OXPHOS). LÄS MER

  5. 5. Phase transitions and phase frustration in multicomponent superconductors

    Författare :Daniel Weston; Egor Babaev; Mats Wallin; Ilya Eremin; KTH; []

    Sammanfattning : Multicomponent superconductors described by several complex matter fields have properties radically different from those of their single-component counterparts. Examples include partially ordered phases and spontaneous breaking of time-reversal symmetry due to frustration between Josephson-coupled components. LÄS MER
