    Abstract : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. READ MORE

  5. 3. Advances in Membrane Protein Structural Biology: Lipidic Sponge Phase Crystallization, Time-Resolved Laue Diffraction and Serial Femtosecond Crystallography

    Author : Linda C Johansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Serial femtosecond crystallography; Lipidic sponge phase crystallization; Membrane protein crystallization; X-ray free-electron laser;

    Abstract : Membrane proteins carry out many essential tasks in cells such as signaling and transport, or function as electron carriers in photosynthesis and cellular respiration. The aim of this thesis has been to develop new and improve existing techniques for elucidating the structure and function of membrane proteins. READ MORE

  6. 4. Structural Insights at Sub-Ångstrom, Medium and Low Resolution: Crystallization of Trypsin, Bacterioferritin, Photosynthetic Reaction Center, and Photosynthetic Core Complex

    Author : Weixiao Yuan Wahlgren; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein crystallization; cubic phase; sponge phase; bicelle; trypsin; bacterioferritin; reaction center; core complex; photosynthesis;

    Abstract : The catalytic action of serine proteases depends on the interplay of a nucleophile, a general base and a general acid. The catalytic triad is composed of serine, histidine and aspartate residues. The serine acts as a nucleophile while the histidine plays a dual role as the general base or acid at different steps of the reaction. READ MORE

  7. 5. Lipidic-sponge phase crystallisation and time-resolved Laue diffraction studies of bacterial photosynthetic reaction centres

    Author : Annemarie Wöhri; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipidic-sponge phase crystallization reaction centre from Rhodobacter sphaeroides and Blastochloris viridis photosynthesis evolution time-resolved Laue diffraction;

    Abstract : Photosynthesis is the procedure of light capture and converting it into a chemical energy source for the cell. The work-horse of this process are photosynthetic reaction centres, which capture photons with the help of their antenna complexes and use these photons to drive charge separation reactions, and ultimately chemiosmotic coupling.
