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

    Author : Daniela Geisler; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Plant type II NAD(P)H dehydrogenases : Structure, regulation and evolution of NDB proteins

    Author : Mengshu Hao; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Ca2 ; Electron transport; NDH-2; NDB; pH; NADH; NADPH; Plant mitochondria; Potato; Type II NAD P H dehydrogenase;

    Abstract : In living organisms, respiration is a biological process degrading different carbon substrates, consuming O2, and releasing the carbon as CO2. Plants have several alternative enzymes that are involved in the respiratory processes, as compared to animals. READ MORE

  3. 3. Pyridine Nucleotides in Plant Mitochondria. Amounts, metabolism and contribution to electron transport

    Author : Stephanie C Agius; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; antibody; Botanik; NAD-pyrophosphatase; Botany; NADH:ubiquinone oxidoreductase; NADPH dehydrogenase; plant mitochondria; pyridine nucleotides;

    Abstract : HPLC analysis was used for direct quantification of amounts and redox levels of pyridine nucleotides in plant mitochondria. The amount of NAD(H) and NADP+ varied, 1.0-3.7 and 0-0. READ MORE

  4. 4. Strain- and bioprocess-design strategies to increase production of (R)-3-hydroxybutyrate by Escherichia coli

    Author : Mónica Guevara-Martínez; Gen Larsson; Antonius J. A. van Maris; Pau Ferrer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; E. coli; R -3-hydroxybutyrate; metabolic engineering; bioprocess design; NADPH; acetic acid; thioesterase; BAC; Bioteknologi; Biotechnology;

    Abstract : Microbial bio-based processes have emerged as an alternative to replace fossil-based processes for the production of fuels and chemicals. (R)-3-hydroxybutyrate (3HB) is a medium-value chemical that has gained special attention as a precursor of antibiotics and vitamins, as a monomer for the synthesis of tailor-made polyesters and as a nutritional source for eukaryotic cells.

  5. 5. Redox balancing in recombinant strains of Saccharomyces cerevisiae

    Author : Mikael Anderlund; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xylose isomerase; xylitol dehydrogenase; xylose reductase; glycerol; xylitol; xylose; E. coli; A. vinelandii; T. thermophilus; S. cerevisiae; P. stipitis; transhydrogenase.; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : In metabolically engineered Saccharomyces cerevisiae expressing Pichia stipitis XYL1 and XYL2 genes, encoding xylose reductase (XR) and xylitol dehydrogenase (XDH), respectively, xylitol is excreted as the major product during anaerobic xylose fermentation and only low yields of ethanol are produced. This has been interpreted as a result of the dual cofactor dependence of XR and the exclusive use of NAD+ by XDH. READ MORE
