  1. 1. 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; Biochemistry; biokemi;

    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

  2. 2. Protein and lipid interactions within the respiratory chain : Studies using membrane-mimetic systems

    Author : Tobias Nilsson; Peter Brzezinski; Petra Hellwig; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Cytochrome c oxidase; ATP synthase; Bioenergetics; membrane-mimetics; Rcf1; liposomes; oxidative phosphorylation; lipids; protein-protein interactions; Biochemistry; biokemi;

    Abstract : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. READ MORE

  3. 3. 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; Biochemistry; biokemi;

    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

  4. 4. 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; Biochemistry; biokemi;

    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

  5. 5. Proton transfer across and along biological membranes

    Author : Johan Berg; Peter Brzezinski; Artur Osyczka; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biological membranes; cardiolipin; cytochrome bo3; cytochrome c oxidase; energy conversion; fluorescence correlation spectroscopy FCS ; localized coupling; mitochondria; proton transfer; Rcf1; respiration; single-enzyme measurement; Biochemistry; biokemi;

    Abstract : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. READ MORE
