1. 1. Structural modeling of membrane transporter proteins

   Författare :Jonas Almqvist; Sven Hovmöller; David van der Spoel; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; membrane protein structure; membrane protein crystallography; membrane protein structure modelling; Structural biochemistry; Strukturbiokemi; strukturkemi; Structural Chemistry;

   Sammanfattning : A fundamental process of all living organisms - the transport of molecules across cellular membranes through membrane transport proteins - is investigated.After a brief review of general properties of biological membranes follows a recollection of the major methods of membrane transport that Nature utilizes (Chapter 1).

3. 2. 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

4. 3. Experimental Protein Dynamics and its Role in Predicting Protein Function

   Författare :Maja Jensen; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biochemistry; Protein Dynamics; Protein Function;

   Sammanfattning : By studying proteins we learn about the processes that control life, such as important procedures in the body, diseases and eventually find more targeted cures for many diseases. Proteins are constantly being built up and decomposed in living organisms. Many proteins move and interact with other proteins or small molecules in the cell. LÄS MER

5. 4. 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

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
