  1. 1. Wiring Components of the Respiratory Chain Modulation of the Respiratory Chain in Yeast and Bacteria

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Jacob Schäfer; Peter Brzezinski; Dennis Winge; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; Electron transfer; Membrane protein; Ligand; Kinetics; Mechanism; Rcf1; Cytochrome c; Respiratory supercomplex; Cryo-electron microscopy; biokemi; Biochemistry;

    Sammanfattning : The enzyme complexes of the respiratory chain are organized in supramolecular assemblies, so-called respiratory supercomplexes. In the yeast Saccharomyces cerevisiae, these supercomplexes consist of two copies of complex III (bc1 complex) and one or two copies of complex IV (cytochrome c oxidase, CytcO). LÄS MER

  2. 2. Mechanistic Insights in the Biogenesis and Function of the Respiratory Chain

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Hannah Dawitz; Martin Ott; Cristina Ugalde; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; respiratory chain; bc1 complex; cytochrome c oxidase; Cbp3; Rcf1; Rcf2; respiratory supercomplexes; biogenesis; mitochondria; Saccharomyces cerevisiae; biokemi; Biochemistry;

    Sammanfattning : Mitochondria fulfill a plethora of functions, including harboring metabolic pathways and converting energy stored in metabolites into ATP, the common energy source of the cell. This last function is performed by the oxidative phosphorylation system, consisting of the respiratory chain and the ATP synthase. LÄS MER

  3. 3. Structural characterisation of mitochondrial macromolecular complexes using cryo-EM Mitoribosome biogenesis and respiratory chain supercomplex

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Sorbhi Rathore; Martin Ott; Daniel Wilson; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; mitoribosome biogenesis; mitoribosome assembly factors; yeast respiratory supercomplexes; single particle electron cryo-microscopy; cryo-EM sample preparation; biokemi; Biochemistry;

    Sammanfattning : Mitochondria, popularly known as powerhouse of the cell, contain specialised mitoribosomes that synthesise essential membrane proteins. These essential proteins are required to form enzyme complexes, which carry out the process of oxidative phosphorylation (OXPHOS). LÄS MER

  4. 4. NADH:quinone oxidoreductase: the black box of the respiratory chain

    Detta är en avhandling från Robert Roth, Dept of Biochemistry, Lund University

    Författare :Robert Roth; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NADH:quinone oxidoreductase; Complex I; electron transport; membrane protein; ubiquinone; respiratory chain; respiration; metabolism; Metabolism; Biokemi; Biochemistry;

    Sammanfattning : Complex I or NADH:quinone oxidoreductase the largest, most complex and least understood of the five membrane-bound enzyme complexes constituting the mitochondrial respiratory chain. The enzyme is present in all types of organisms, from bacteria to mammals. LÄS MER

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

    Detta är en avhandling från Lund University Department of Cell and Organism Biology Sölvegatan 35B SE-223 62 Lund

    Författare :Daniela Geisler; [2007]
    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
