  1. 1. Implementation and development of serial synchrotron crystallography at MAX IV

    Författare :Bjelčić Monika; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ssx; time-resolved; crystallography; MAX IV LAboratory;

    Sammanfattning : Over the past decade, remarkable advancements in femtosecond X-ray free-electron lasers (XFELs) have brought about a profound transformation in structural biology. These XFELs have opened up exciting opportunities for conducting high-time resolution, room-temperature studies on protein structures and dynamics. LÄS MER

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

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Serial femtosecond crystallography; Lipidic sponge phase crystallization; Membrane protein crystallization; X-ray free-electron laser;

    Sammanfattning : 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. LÄS MER

  4. 3. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin

    Författare :Robert Bosman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rhodopsin; SRII; SRII-HtrII; Time-resolved crystallography; Time-resolved wide angle x-ray scattering; TR-X; TR-WAXS; Serial crystallography;

    Sammanfattning : Responding to different light conditions is an essential process for many organisms on earth. Unicellular organisms are no exception to this and mechanisms for controlling cellular movement must often be sensitive to light. LÄS MER

  5. 4. Structural studies of ba3-type cytochrome c oxidase using serial crystallography and X-ray absorption spectroscopy

    Författare :Doris Zoric; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ba3-type cytochrome c oxidase; structural biology; X-rays; serial X-ray crystallography; X-ray absorption spectroscopy; enzyme reaction dynamics;

    Sammanfattning : Cytochrome c oxidase (CcO) catalyses the reduction of molecular oxygen to water while the energy released in this process is used transport protons “up-hill” across an energy transducing biological membrane, creating a proton-motive force for ATP synthesis. Given its key role in energy transduction in organisms, proton pumping has been extensively studied across species. LÄS MER

  7. 5. The Primary Structural Photo-Response of a Bacterial Phytochrome Probed by Serial Femtosecond Crystallography

    Författare :Elin Claesson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoreceptors; Phytochromes; SFX;

    Sammanfattning : Species across all kingdoms of life rely on the ability to sense different light conditions. Some organisms convert light into chemical energy via the reactions involved in photosynthesis, whereas others use it to trigger cellular signals. The group of proteins that are responsible for light perception are called photoreceptor proteins. LÄS MER
