  1. 1. Major Intrinsic Proteins - Structure, function, interactions

    Författare :ANDREAS KIRSCHT; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporin; membrane proteins; crystallography; stopped-flow; molecular dynamics; structure modeling;

    Sammanfattning : Major intrinsic proteins, also referred to as aquaporins (AQPs) are localized in membranes of all domains of life to increase the permeability to water or other small, polar molecules. Several monophyletic groups can be discerned in this large and divergent protein superfamily. LÄS MER

  3. 2. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

    Författare :Péter Nagy; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

    Sammanfattning : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

  4. 3. Equilibrium and Kinetic Studies of the Binding of DNA to Cationic Liposomes

    Författare :Paula Barreleiro; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small-Angle Neutron Scattering; Fluorescence; Kinetics; Stopped-Flow; Differential Scanning Calorimetry; Titration Calorimetry; Gel-to-Liquid Crystalline Phase Transition; Lamellar phase; Lipolexes; DNA; Liposomes; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The objective of this work was to study the formation of DNA-cationic vesicle complexes (lipoplexes). These complexes are interesting not only from a fundamental point of view but also as promising candidates for gene therapy. The approach taken was to study first the cationic vesicles by themselves.

  5. 4. Effects of Macromolecular Crowding on Protein Folding : - in-vitro equilibrium and kinetic studies on selected model systems

    Författare :Alexander Christiansen; Pernilla Wittung-Stafshede; Thomas Kiefhaber; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein Folding; macromolecular crowding; excluded volume; spectroscopy; stopped-flow; biokemi; Biochemistry;

    Sammanfattning : Protein folding is the process during which an extended and unstructured polypeptide converts to its compact folded structure that is most often the functional state. The process has been characterized extensively in dilute buffer in-vitro during the last decades but the actual biological place for this process is the inside of living cells. LÄS MER

    Författare :Maja Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electrophoresis; cyanide dyes; dissociation kinetics; minor groove binding; DNA; stopped-flow; unwinding; mobility shift assays;
