  1. 11. Strategies to explore the membrane proteome of a cell

    Författare :Gianluca Maddalo; Leopold L. Ilag; Peter James; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteomics; Escherichia coli; Enterococcus faecalis; Synechocystis; Mass Spectrometry; BN SDS-PAGE; FT-ICR-MS; Myelin P2 protein; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The cell envelope plays key roles in numerous processes such as maintaining cellular integrity, communication with other cells, signal transduction, maintenance of cellular homeostasis, and regulation of the traffic of molecules between the cell and the extracellular milieu. Essential membrane components in many of these processes are proteins. LÄS MER

  4. 13. Membrane Protein Biogenesis in Escherichia coli : A proteomics approach

    Författare :David Vikström; Jan-Willem de Gier; Eitan Bibi; Stockholms universitet; []
    Nyckelord :SRP; YidC; SecE; Membrane protein biogenesis; protein targeting; 2D BN SDS-PAGE; Biochemistry; biokemi;

    Sammanfattning : In the bacterium Escherichia coli all proteins are synthesized in the cytoplasm. However, at least 25% of them then need to be exported to another cellular compartment where they exert their function. E. coli has several different targeting pathways to ensure the correct localization of its proteins. LÄS MER

  5. 14. Protein-surfactant interactions

    Författare :Ank Valstar; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. LÄS MER

  7. 15. Molecular dynamics and aggregation behaviour in aqueous polymer-drug model systems

    Författare :Hans Evertsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry; fysikalisk och oorganisk farmaceutisk kemi;

    Sammanfattning : Pharmaceutical formulations often contain polymers used as binders, swelling agents, etc., to give the formulation mechanical stability or specific drug release features. Many drug substances, as well as polymers, are amphiphilic which will give an associative polymer-drug interaction, affecting the dissolution rate and drug release. LÄS MER
