  2. 1. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin

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

    Abstract : 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. READ MORE

  4. 2. From Time-Averaged to Time-Resolved Crystallography: Studies on Superoxide Dismutase and Myoglobin

    Author : Thomas Ursby; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; superoxide dismutase; Bayesian statistics; electron difference maps; synchrotron; docking site; photolysis; myoglobin; Time-resolved crystallography; Laue; thermostability; Sulfolobus solfataricus; Molecular biophysics; Molekylär biofysik;

    Abstract : We have studied protein motions with nanosecond time-resolved crystallography. The release of carbon monoxide from its complex with myoglobin (MbCO) was triggered by nanosecond laser pulses. X-ray data were collected with time delays ranging from 4 ns to 1.9 ms using the Laue method, at the European Synchrotron Radiation Facility in Grenoble. READ MORE

  5. 3. Implementation and development of serial synchrotron crystallography at MAX IV

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

    Abstract : 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. READ MORE

  6. 4. Generation and Applications of Short-Pulse X-ray Radiation

    Author : Michael Harbst; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; egenskaper termiska och mekaniska ; Kondenserade materiens egenskaper:struktur; crystallography; phase equilibria; Material science; Condensed matter:stucture; thermal and mechanical properties; time-resolved; X-ray diffraction; kristallografi; fasjämvikt; Material technology; Materiallära; materialteknik;

    Abstract : This thesis summarizes work using hard X-ray radiation on nanosecond and picosecond timescales. The focus is on the experimental part including detailed descriptions of setups for laser pumped - X-ray probe experiments. X-ray diffraction is sensitive to structural properties on the length scale of chemical bonds. READ MORE

  7. 5. Crystallography in Four Dimensions : Methods and Applications

    Author : Gunilla Carlsson; Janos Hajdu; Dieter Oesterhelt; Vilmos Fülöp; Uppsala universitet; []

    Abstract : The four-electron reduction of dioxygen to water is the most exothermic non-photochemical reaction available to biology. A detailed molecular description of this reaction is needed to understand oxygen-based redox processes. Horseradish peroxidase (HRP) is a haem-containing redox enzyme capable of catalysing the reduction of dioxygen to water. READ MORE
