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

    Detta är en avhandling från Thomas Ursby, Molecular Biophysics, Chemical Center, Lund University

    Författare :Thomas Ursby; [1998]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Production and Structural Dynamics of Microbial Rhodopsins

    Detta är en avhandling från Göteborgs universitet

    Författare :Cecilia Wickstrand; Göteborgs universitet.; Gothenburg University.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteriorhodopsin; channelrhodopsin; time-resolved serial femtosecond crystallography;

    Sammanfattning : Rhodopsins are a family of membrane proteins that are found in a wide range of organisms and provide them with the ability to sense and react to light. When light is absorbed by these proteins, structural changes occur that initiate the pumping of protons, opening of a channel or signal transfer. LÄS MER

  4. 4. Cubic Cell Membrane Architectures. Taking another look at membrane bound cell spaces

    Detta är en avhandling från Department of Food Technology, Lund University

    Författare :Tomas Landh; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; projections; image analysis; periodic cubic surfaces; membrane morphology; cubic membranes; cell ultrastructure;

    Sammanfattning : A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations.

  5. 5. The hematopoietic transcription factor RUNX1 a structural view

    Detta är en avhandling från Umeå : Umeå centrum för molekylär patogenes (UCMP) (Teknisk-naturvetenskaplig fakultet)

    Författare :Stefan Bäckström; Umeå universitet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; RUNX1; Runt domain; CBFβ; transcription factor; leukaemia; protein crystallography; anomalous diffraction; Molekylärmedicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Molecular medicine genetics and pathology ; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Molekylär medicin genetik och patologi ; molekylärbiologi; Molecular Biology;

    Sammanfattning : The malfunction of the transcriptional regulator RUNX1 is the major cause of several variants of acute human leukemias and its normal function is to regulate the development of the blood system in concert with other transcriptional co-regulators. RUNX1 belongs to a conserved family of heterodimeric transcription factors that share a conserved DNA binding domain, the Runt domain (RD), named after the first member of this group – Runt - found in Drosophila melanogaster.
