1. 1. Human Aquaporins: Production, Characterization and Interactions

   Författare :Jennie Sjöhamn; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporins; membrane protein; protein production; protein characterization; protein:protein interactions; structural biochemistry;

   Sammanfattning : Membrane proteins are essential components of the cell and responsible for the communication with the outside environment and transport of molecules across the membrane. Water transport is facilitated by aquaporins, which are water selective transmembrane pores that serve to maintain cell homeostasis. LÄS MER

3. 2. Advances in Membrane Protein Structural Biology: Lipidic Sponge Phase Crystallization, Time-Resolved Laue Diffraction and Serial Femtosecond Crystallography

   Författare :Linda C Johansson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Serial femtosecond crystallography; Lipidic sponge phase crystallization; Membrane protein crystallization; X-ray free-electron laser;

   Sammanfattning : Membrane proteins carry out many essential tasks in cells such as signaling and transport, or function as electron carriers in photosynthesis and cellular respiration. The aim of this thesis has been to develop new and improve existing techniques for elucidating the structure and function of membrane proteins. LÄS MER

4. 3. Structural studies on the integral membrane protein, ubiquinol oxidase from Escherichia coli

   Författare :Jeff Abramson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; crystal structure; ubiquinol oxidase; membrane protein; oxidases; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : Heme-copper oxidases are redox-driven proton pumps that couple the reduction of molecular oxygen to water with the vectorial translocation of protons across the membrane. The proton gradient generated by heme-copper oxidases and the other members of the aerobic respiratory chain is ultimately used to drive the synthesis of ATP. LÄS MER

5. 4. On the crystallization of membrane proteins in lipidic sponge and cubic phases

   Författare :Pia Jeanette Hindrichsen; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

   Sammanfattning : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. LÄS MER

7. 5. Plant aquaporin regulation: Structural and functional studies using diffraction and scattering techniques

   Författare :Michael Järvå; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray Crystallography; Membrane protein; Plasma membrane intrinsic protein; Aquaporin; pH gating; mercury; proteoliposome assay; water transport; SANS; SAXS; WAXS; nanodisc; liposome;

   Sammanfattning : Water is the basis for life as we know it. It is only logical then that all organisms have evolved specialized proteins, aquaporins, which regulate water flow across their membranes. Plants, which are immobile, depend more on their environment and also use water flows to move, to breathe, and to grow. LÄS MER
