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

    University dissertation from Thomas Ursby, Molecular Biophysics, Chemical Center, Lund University

    Author : Thomas Ursby; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian statistics; superoxide dismutase; 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

    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

    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
