  2. 2. The Ins and Outs of Membrane Proteins : Topology Studies of Bacterial Membrane Proteins

    Author : Mikaela Rapp; Gunnar von Heijne; Christopher Tate; Stockholms universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane protein; topology; dual topology; Biochemistry; Biokemi;

    Abstract : α-helical membrane proteins comprise about a quarter of all proteins in a cell and carry out a wide variety of essential cellular functions. This thesis is focused on topology analyses of bacterial membrane proteins. The topology describes the two-dimensional structural arrangement of a protein relative to the membrane. READ MORE

  3. 3. Contributions to Pointfree Topology and Apartness Spaces

    Author : Anton Hedin; Erik Palmgren; Viggo Stoltenberg-Hansen; Peter Schuster; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Constructive mathematics; General topology; Pointfree topology; Domain theory; Interval analysis; Apartness spaces; Mathematical logic; Matematisk logik; Mathematical Logic; Matematisk logik;

    Abstract : The work in this thesis contains some contributions to constructive point-free topology and the theory of apartness spaces. The first two papers deal with constructive domain theory using formal topology. READ MORE

  4. 4. Engineering membrane proteins for production and topology

    Author : Stephen Toddo; Daniel Daley; Roslyn Bill; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; Over-expression; Protein production; Codon optimization; Escherichia coli; AraH; NarK; mRNA secondary structure; coding sequence; ribosome binding site; RBS; topology; split-GFP; Biochemistry; biokemi;

    Abstract : The genomes of diverse organisms are predicted to contain 20 – 30% membrane protein encoding genes and more than half of all therapeutics target membrane proteins. However, only 2% of crystal structures deposited in the protein data bank represent integral membrane proteins. READ MORE

  5. 5. Topology Meets Frustration : Exact Solutions for Topological Surface States on Geometrically Frustrated Lattices

    Author : Flore Kunst; Emil Bergholtz; Jack Lidmar; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : One of the main features of topological phases is the presence of robust boundary states that are protected by a topological invariant. Famous examples of such states are the chiral edge states of a Chern insulator, the helical edge states of a two-dimensional Z2 insulator, and the Fermi arcs of Weyl semimetals. READ MORE
