  1. 6. Membrane-mimetic systems : Novel methods and results from studies of respiratory enzymes

    Författare :Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; Biochemistry; biokemi;

    Sammanfattning : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.

  3. 7. The Ins and Outs of Membrane Proteins : Topology Studies of Bacterial Membrane Proteins

    Författare :Mikaela Rapp; Gunnar von Heijne; Christopher Tate; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane protein; topology; dual topology; Biochemistry; Biokemi;

    Sammanfattning : α-helical membrane proteins comprise about a quarter of all proteins in a cell and carry out a wide variety of essential cellular functions. This thesis is focused on topology analyses of bacterial membrane proteins. The topology describes the two-dimensional structural arrangement of a protein relative to the membrane. LÄS MER

  4. 8. Downstream Processing Using Membrane Technology

    Författare :Anna Persson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biochemical technology; Chemical technology and engineering; Protein A; Bovine serum albumin; Lactic acid; Electrodialysis; Ultrafiltration; Microfiltration; Downstream processing; Membrane; Biokemisk teknik;

    Sammanfattning : Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. LÄS MER

  5. 9. Lysosomal Membrane Permeabilization : A Cellular Suicide Strategy

    Författare :Ann-Charlotte Johansson; Karin Öllinger; Karin Roberg; Boris Zhivotovsky; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apoptosis; lysosomes; lysosomal membrane permeabilization; cathepsins; Bax; Bid; mitochondria; caspases; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : In the last decade, a tremendous gain in knowledge concerning the molecular events of apoptosis signaling and execution has been achieved.The aim of this thesis was to clarify the role of lysosomal membrane permeabilization and lysosomal proteases, cathepsins, in signaling for apoptosis.

  7. 10. Cell Membrane Homeostasis in Mammals - The roles of ADIPOR2 and TLCD1 & 2

    Författare :Henrik Palmgren; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; Membrane fluidity; Membrane homeostasis; Dietary lipids; Phospholipids; Genetics; Lipotoxicity; Lipidomics; ADIPOR2; TLCD1; TLCD2;

    Sammanfattning : Ten nanometers. That is the approximate thickness of the plasma membrane that separates the extracellular space from the entire cellular machinery. An asymmetrical bilayer consisting of predominantly phospholipids in which proteins and carbohydrates are anchored and exert their function. LÄS MER
