  1. 1. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering

    Författare :Oskar Berntsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; Photoreceptor; Time-resolved X-ray solution scattering; Protein dynamics; Phytochrome; Light-oxygen-voltage; Cryptochrome;

    Sammanfattning : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. LÄS MER

  2. 2. Conformational Dynamics of Rhodopsins Visualized by Time-resolved Wide Angle X-ray Scattering

    Författare :Erik Malmerberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Time-resolved wide Angle X-ray Scattering; Retinylidene proteins; Rhodopsin; Bacteriorhodopsin; Proteorhodopsin;

    Sammanfattning : Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy to perform a variety of different biological functions. LÄS MER

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

    Författare :Robert Bosman; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :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

  4. 4. Scattering Studies of Macromolecules in Solution

    Författare :David Löf; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bacteriophage lambda; Dynamic Light Scattering; Time-Resolved; Mixed Micelles; Nonionic Surfactant; Triblock Copolymer; Calorimetry; SLS; Rheology; DLS; SAXS;

    Sammanfattning : The sphere-to-rod transition of nonionic micelles of the PEO-PPO-PEO triblock copolymer P123 and the surfactant C12EO6 was studied using dynamic and static light scattering, small angel X-ray scattering, rheology and calorimetry. The transition temperature was dependent of the C12EO6/P123 molar ratio, which means that a larger content of C12EO6 yields a higher transition temperature. LÄS MER

  5. 5. X-ray free-electron laser based methods for structural and ultrafast dynamics studies of a photosynthetic reaction centre

    Författare :David Arnlund; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :WAXS; wide-angle x-ray scattering; XFEL; x-ray free-electron laser; reaction center; structural biology; ultrafast dynamics;

    Sammanfattning : Life on earth is fuelled by the energy of sunlight, which must first be captured and converted into a chemical energy form useful to the cell. This process is known as photosynthesis and the major pathway of this energy conversion is via photosynthetic reaction centres. LÄS MER
