  2. 6. Time-resolved X-ray diffraction and solution scattering studies of Sensory Rhodopsin II in isolation and in complex with its transducer

    Author : Giorgia Ortolani; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; light-activated membrane protein; microbial Rhodopsins; Sensory rhodopsin II; SRII; SRII:HtrII; transducer; SSX; XSS; time-resolved;

    Abstract : Light is an important source of energy for many living organisms. Many life forms have therefore evolved cellular receptors that are able to sense light and thereby optimise conditions for photosynthesis and pho- totrophy. READ MORE

  4. 7. 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

  5. 8. Ultrafast Structural Changes in a Bacterial Photosynthetic Reaction Center probed with XFEL Radiation

    Author : Robert Dods; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Reaction Center; Time-resolved crystallography; XFEL; membrane protein;

    Abstract : Photosynthesis is the process by which plants and many species of bacteria convert energy from sunlight into chemical energy used to power their metabolism. As these plants and bacteria are eaten, the chemical energy moves up the food chain and thus photosynthesis provides fuel for almost all life on Earth. READ MORE

  6. 9. Lipidic Cubic Phase Microcrystallization and its Application in Serial Crystallography

    Author : Rebecka Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structural biology; Lipidic Cubic Phase; Cytochrome c oxidase; Serial Crystallography;

    Abstract : Every living organism contain a cell membrane which is an important cell structure with a vast variety of different functions such as cell signaling, transportation and energy production. One of the most important functions is to produce energy for the cell to thrive. READ MORE

  7. 10. Structural and physicochemical studies on metal and porphyrin binding by the Bacillus subtilis ferrochelatase

    Author : Mattias Hansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal specificity; metal binding; porphyrin metallation; time resolved crystallography; fluorescence quenching; X-ray structure; inclusion bodies; Bacillus subtilis; heme biosynthesis; ferrochelatase; hemH;

    Abstract : The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. READ MORE
