  1. 1. Borrelia channel-forming proteins : structure and function

    Författare :Ignas Bunikis; Sven Bergström; Steven Norris; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Lume disease; relapsing fever; BesC; drug efflux; DipA; P66; porins; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Borrelia is a Gram-negative, corkscrew-shaped bacterium transmitted by infected ticks or lice. Borreliae are subdivided into pathogens of two diseases: Lyme disease, caused mainly by B. burgdorferi, B. afzelii and B. LÄS MER

  3. 2. Porins of Borrelia burgdorferi

    Författare :Marija Pinne; Sven Bergström; Magnus Höök; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lyme disease; P13; paralog; P66; channel-forming activity; porin; Medical microbiology; Medicinsk mikrobiologi;

    Sammanfattning : Borrelia burgdorferi is a pathogenic spirochete which cycles between its arthropod vector and vertebrate host. If transmitted to humans, B. burgdorferi causes Lyme disease, an infection which can impair different organs, such as the skin, joints, nervous system and heart. LÄS MER

  4. 3. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases

    Författare :Fredrik Johansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; morphology; taxonomy; Systematic botany; plant mitochondria; NAD P H dehydrogenases; cold treatment; complex I; light dependence; antimycin a; alamethicin;

    Sammanfattning : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. LÄS MER

  5. 4. Alternative NAD(P)H dehydrogenases in plant mitochondria - localisation, catalytic functions and physiological roles

    Författare :Agnieszka Michalecka; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kärlväxters fysiologi; Physiology of vascular plants; NAD P H dehydrogenase; light-dependence; electron transport chain; alamethicin; alternative oxidase;

    Sammanfattning : In addition to complex I, the plant mitochondrial electron transport chain possesses several alternative NAD(P)H dehydrogenases, not present in animals. These enzymes allow nonenergy-conserving electron transfer from cytoplasmic and matrix NAD(P)H to ubiquinone. LÄS MER

  7. 5. Structure, Function and Regulation of Fps1p. A Eukaryotic Solute Efflux Channel

    Författare :Kristina Hedfalk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NPA-motif; Fps1p; regulation; overexpression; osmoadaptation; glycerol facilitator; MIP;

    Sammanfattning : Integral membrane proteins belonging to the Major Intrinsic Protein (MIP) family can be found in all kingdoms of life. MIPs are transporters of water, small neutral solutes and possibly ions, and hence are important for osmoregulation at different levels. LÄS MER
