  1. 1. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways

    Författare :Daniela Geisler; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteins; Kärlväxters fysiologi; Physiology of vascular plants; Växtekologi; Plant ecology; Växtbiokemi; Plant biochemistry; respiratory chain; plant mitochondria; nitrogen; NADPH dehydrogenase; NADH dehydrogenase; alternative oxidase; calcium; Proteiner; enzymologi; Bioenergetics; Bioenergetik; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Sammanfattning : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. LÄS MER

  3. 2. Microbial production of 3-hydroxypropionic acid and poly(3-hydroxypropionate): Investigation of Lactobacillus reuteri propanediol utilization pathway enzymes

    Författare :Ramin Sabet Azad; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platform chemicals; biopolymers; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; glycerol; poly 3-hydroxypropionate ; polyhydroxyalkanoates; Escherichia coli; Lactobacillus reuteri; propanediol utilization pathway; propionaldehyde dehydrogenase; biotransformation; cofactor regeneration; NADH oxidase;

    Sammanfattning : Concerns regarding environmental issues such as greenhouse gas emissions and climate change have led to a shift within the research community and chemical and energy industry sectors for finding sustainable routes for producing fuels and chemicals from renewable resources, thereby minimizing our dependence on petroleum. The C3-chemical 3-hydroxypropionic acid has been identifed as a top candidate for the biobased chemical industry. LÄS MER

  4. 3. Discovery of N-hydroxyguanidines as novel electron acceptors of xanthine oxidase : Potential new drugs for treatment of ischemia and reperfusion injury

    Författare :Maija Dambrova; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; xanthine oxidase; N-hydroxyguanidine derivatives; ischemia and reperfusion; reduction; inhibition; superoxide; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

    Sammanfattning : Xanthine oxidase (EC 1.1.3.22) is one of the major enzymatic sources of oxygen-derived free radicals. 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. Development of Second and Third Generation Bioelectronics

    Författare :Federico Tasca; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow injection analysis; amperometric biosensor; mediated electron transfer; direct electron transfer; tryptophan repressor-binding protein; diaphorase; pyranose oxidase; cellobiose dehydrogenase; pyranose dehydrogenase; biofuel cell; spectroelectrochemistry; single wall carbon nanotubes; bioelectronics.;

    Sammanfattning : The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”.
