  1. 21. Structural studies of proteins in apoptosis and lipid signaling

    Författare :Maria Dolores Herman Moreno; Pär Nordlund; Markus Gruetter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteins; crystal structure; apoptosis; cancer; CoFi-Blot; kinases; lipid signaling; Structural biology; Strukturbiologi; Structural Biology; strukturbiologi;

    Sammanfattning : Signaling pathways control the fate of the cell. For example, they promote cell survival or commit the cell to death (apoptosis) in response to cell injury or developmental stimuli, decisions, which are vital for the proper development and functioning of metazoan. LÄS MER

  3. 22. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

    Författare :Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

    Sammanfattning : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. LÄS MER

  4. 23. Membrane protein proteomics - Novel method for membrane protein identification and quantification

    Författare :Maria Bentz; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biokemisk teknik; mebran; steroider; Lipider; membranes; steroids; Lipids; enzymologi; Proteiner; Membrane proteins; Proteomics; Proteinase K; N-terminal labelling; Relative Quantitation; Database search; Cancer; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; enzymology; Proteins; Biochemical technology;

    Sammanfattning : Membrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. LÄS MER

  5. 24. Protein production in the E. coli cell envelope

    Författare :Thomas Baumgarten; Jan-Willem de Gier; Dirk-Jan Scheffers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; E. coli; protein biogenesis; recombinant proteins; membrane proteins; secretory proteins; protein displays; outer membrane vesicles; Biochemistry; biokemi;

    Sammanfattning : Proteins fulfil essential functions in every cell and malfunctioning proteins are often the cause of diseases. On the other hand, proteins like antibody fragments or hormones can be used to treat diseases. LÄS MER

  7. 25. Separation Methods in Membrane Proteomics -Integration of Aqueous Two-Phase Partitioning for Enrichment and Pre-Fractionation

    Författare :Henrik Everberg; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteins; metabolism; Biokemi; Metabolism; Biochemistry; Aqueous two-phase partitioning; enzymology; Proteiner; enzymologi; Proteomics;

    Sammanfattning : The study of the protein complement of a genome is called proteomics. Proteomics can be defined as identification, quantification and characterization of a total set of proteins expressed at different time-points or under different cellular states to provide global information about biological processes.
