  1. 1. Visualizing structural dynamics: from small molecules to membrane proteins

    Författare :Magnus Andersson; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane protein; bacteriorhodopsin; proteorhodopsin; halorhodopsin; structural dynamics; time-resolved X-ray scattering;

    Sammanfattning : To fully understand the mechanism of a chemical reaction, it is important to characterize the rapid structural dynamics of transient chemical species as the reaction propagates. Since chemical processes are heavily influenced by the solvent in which they occur, the interaction with the surrounding solution also needs to be elucidated. LÄS MER

  2. 2. Painfully Energetic : A tale of two proteins potentially connected

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry, Division of Biochemistry and Structural Biology

    Sammanfattning : Varje cell har ett membran som skapar en gräns mot omvärlden och skyddarcellen. Men cellen måste alltjämt utbyta viktiga molekyler med omvärlden för attöverleva. Därför finns specialiserade proteiner, som sitter i membranen och utgörportar i denna barriär. LÄS MER

  3. 3. Exploring Unorthodox Aquaporins : Characterization of NbXIPs & AtNIPs

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry, Division of Biochemistry and Structural Biology

    Författare :Henry Ampah-Korsah; Lunds universitet.; Lund University.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporins; XIPs; NIPs; Phosphorylation; Pichia pastoris; Overexpression; boric acid; membrane proteins;

    Sammanfattning : Popular science summaryWater is very important for life. In order to survive every organism needs to control the amount of water in its cells. One of the main ways the cell regulates its water content is through aquaporins. Aquaporins are membrane proteins that allow water and/or small neutral molecules to enter or exit the cell. LÄS MER

  4. 4. Transthyretin and the transthyretin-related protein: A structural study

    Detta är en avhandling från Umeå : Umeå centrum för molekylär patogenes (UCMP) (Teknisk-naturvetenskaplig fakultet)

    Författare :Erik Lundberg; Umeå universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Transthyretin-related protein; X-ray crystallography; Protein structure; Amyloidosis; NATURAL SCIENCES Chemistry Biochemistry Structural biology; NATURVETENSKAP Kemi Biokemi Strukturbiologi;

    Sammanfattning : Transthyretin (TTR) is one of several proteins involved in amyloid disease in humans. Unknown conformational changes of the native state of TTR result in aggregation of TTR molecules into amyloid fibrils, which accumulate in extracellular tissues. This may result in different clinical symptoms, e.g. LÄS MER
