  1. 21. Structural analysis of microsomal glutathione transferase 1 by electron crystallography

    Författare :Ingeborg Schmidt-Krey; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The goals of this project were the two-dimensional crystallization of the membrane protein microsomal glutathione transferase 1 and the three-dimensional structure determination by electron crystallography. Microsomal glutathione transferase 1 is a homotrimeric membrane protein. LÄS MER

  3. 22. From Sequence to Structure- Characterizing Human and Plant Aquaporins

    Författare :Kristina Nordén; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Aquaporins constitute a class of membrane proteins that create pores through the lipid bilayer of biological membranes, facilitating the passage of water and other small solutes. Nearly all living organisms possess a more or less intricate set up of aquaporin proteins and the importance of these channels has been implicated in many aspects of health and disease. LÄS MER

  4. 23. 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. 24. X-ray free-electron laser based methods for structural and ultrafast dynamics studies of a photosynthetic reaction centre

    Författare :David Arnlund; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

  7. 25. Quantitation, Purification and Reconstitution of the Red Blood Cell Glucose Transporter GLUT1

    Författare :Shusheng Zuo; Bengt Mannervik; Bengt Persson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Cholesterol; Cytochalasin B; Glucose; GLUT1; Hummel and Dreyer analysis; Immobilization; PEG 5000 -DSPE; Biomembrane; Proteoliposome; Quantitative frontal affinity chromatography; Red blood cell streptavidin-biotin immobilization; Sulfhydryl affinity chromatography; The modified micro-Bradford CaPE assay; MALDI-ToF-MS; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : The human glucose transporter GLUT1 facilitates glucose to be accumulated on the other side of the cell membrane. The functional state of GLUT1 is uncertain due to diversity of the reports. In this thesis, the activity of red blood cell GLUT1 was extensively studied to further characterize this protein. LÄS MER
