  1. 11. 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. 12. Plasma membrane arabinogalactan proteins

    Författare :Lars Snogerup; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arabinogalactan protein plant development cell-cell interaction plasma membrane; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Arabinogalactan proteins (AGPs) are proteoglycans found at the outer side of the plasma membrane and in the extracellular matrix of plants. To be able to study the plasma membrane bound AGPs, a method using SDS-agarose gel electrophoresis (SDS-AGE) was developed to overcome the problems associated with electrophoretic separation of highly glycosylated proteins.

  4. 13. Xanthophyll Cycle in the Light of Thylakoid Membrane Lipids - Membrane Packing, Curvature Elastic Stress and Enzyme Binding

    Författare :Anna Szilagyi; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; steroider; Lipids; steroids; membranes; Lipider; enzymologi; HPLC; laurdan; fluorescence spectroscopy; Proteins; enzymology; Proteiner; curvature elastic stress; enzyme binding; thylakoid membrane; membrane fluidity; lipid packing; histidine; VDE; zeaxanthin; xanthophyll cycle; mebran;

    Sammanfattning : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. The enzyme, violaxanthin de-epoxidase (VDE) catalyses the conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin. VDE is a membrane-hosted enzyme during its activity. LÄS MER

  5. 14. Uncoupling Proteins : Regulation by IGF-1 and Neuroprotection during Hyperglycemia in Vitro

    Författare :Helena Gustafsson; Anna Forsby; David Tomlinson; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; uncoupling protein; oxidative stress; diabetes; neuropathy; SH-SY5Y; Neurobiology; Neurobiologi;

    Sammanfattning : Diabetic neuropathy is believed to arise due to oxidative stress following hyperglycemic situations. Uncoupling proteins (UCPs) constitute a subgroup of mitochondrial transporter proteins with putative antioxidant properties. LÄS MER
