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

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

    Abstract : 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. READ MORE

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

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Biochemistry and Structural Biology

    Author : Eva Sperling; Lund University.; Lunds universitet.; [2017-03]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Complex I; Mrp-antiporter; Membrane bound hydrogenases; TRP ion channels; TRPA1; thermosensation; chemosensation; 23Na-NMR;

    Abstract : NADH:quinone oxidoreductase (Complex I) is the first enzyme of the respiratory chain and is involved in energy conservation generating an electro-chemical gradient across a membrane. The enzyme can be divided into a membrane spanning domain and a hydrophilic domain, which protrudes from the membrane. READ MORE

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

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Biochemistry and Structural Biology

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

    Abstract : AbstractAquaporins are membrane integral proteins that facilitate the transport of waterand/or other small neutral molecules across biological membranes in cells in allforms of life. Among the subfamilies of aquaporins in higher plants, the X IntrinsicProteins (XIPs) are the most recently discovered subfamily and the leastcharacterized. READ MORE

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

    University dissertation from Umeå : Umeå centrum för molekylär patogenes (UCMP) (Teknisk-naturvetenskaplig fakultet)

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

    Abstract : 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. READ MORE
