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

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

    Abstract : 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). READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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). READ MORE

  4. 4. Significance of mitochondrial ultrastructure for bioenergetics

    Author : Alexandra Toth; Martin Ott; Vladimir Gogvadze; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; bioenergetics; mitochondrial ultrastructure; respiratory chain; Saccharomyces cereviciae; ATP synthase; apoptosis; cytochrome c; supercomplexes; biokemi; Biochemistry;

    Abstract : Mitochondria are the site where most of the energy from food is converted into adenosine triphosphate (ATP). This process is taking place at the inner membrane (IM) of mitochondria, and is called oxidative phosphorylation, and results in the establishment of a proton motive force (pmf). READ MORE

  5. 5. Modulators of Saccharomyces cerevisiae cytochrome c oxidase : Implications for the regulation of mitochondrial respiration

    Author : Camilla Rydström Lundin; Peter Brzezinski; Christoph von Ballmoos; Shelagh Ferguson-Miller; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; cytochrome c; OXPHOS; membrane protein; kinetics; ligand-binding; electron transfer; Rcf1; respiratory supercomplexes; Saccharomyces cerevisiae; biokemi; Biochemistry;

    Abstract : Oxidative phosphorylation in mitochondria is performed by enzyme complexes and electron carriers that reside in the inner membrane. It is now generally accepted that these respiratory enzyme complexes assemble into larger so-called supercomplexes. However, it is presently not known why, under which conditions or how these supercomplexes form. READ MORE
