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

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

    Sammanfattning : 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. LÄS MER

  3. 12. Nitrogen and Redox Metabolism in Saccharomyces cerevisiae

    Författare :Eva Albers; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces cerevisiae; glutamate; protein expression; anaerobic physiology; nitrogen metabolism; redox; serine;

    Sammanfattning : Anaerobic conversion of glucose to ethanol by the yeast Saccharomyces cerevisiae has been studied. Glycerol is formed as a by-product in order to maintain the overall redox balance. LÄS MER

  4. 13. A kinetic study of metabolite transfer in coupled two-enzyme reactions

    Författare :Henrik Pettersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Free diffusion; Enzyme kinetics; Channelling; Dehydrogenase; Fusion protein; Biochemistry; Proximity effect; metabolism; Biokemi;

    Sammanfattning : There are two fundamentally different ways by which a metabolite can be transferred between enzymes in metabolic pathways. If the two sequential enzymes cannot form a complex with each other, the metabolite must first be released from the producing enzyme to the reaction medium and then be transported to the consuming enzyme, via the reaction medium, by free diffusion.

  5. 14. Structural and mechanistic aspects of alcohol dehydrogenase function

    Författare :Stefan Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Vertebrates possess a complex alcohol dehydrogenase (ADH) system composed of multiple molecular forms, which are currently classified into seven classes according to their structural properties. ADHs are dimeric zinc metalloenzymes that catalyze the reversible oxidation of alcohols to aldehydes/ketones using NAD+/NADH as electron acceptor and donor, respectively. LÄS MER
