  2. 1. Early steps in the biogenesis of the bc1 complex in yeast mitochondria : The role of the Cbp3-Cbp6 complex in cytochrome b synthesis and assembly

    Author : Steffi Gruschke; Martin Ott; Dennis Winge; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mitochondria; respiratory chain assembly; bc1 complex; mitochondrial gene expression; translational regulation; hemylation; Biochemistry; biokemi;

    Abstract : The inner membrane of mitochondria harbors the complexes of the respiratory chain and the ATP synthase, which perform the key metabolic process oxidative phosphorylation. These complexes are composed of subunits from two different genetic origins: the majority of constituents is synthesized on cytosolic ribosomes and imported into mitochondria, but a handful of proteins, which represent core catalytic subunits, are encoded in the organellar DNA and translated on mitochondrial ribosomes.

  4. 2. Biogenesis of the bc1 complex in mitochondria

    Author : Katharina Stephan; Martin Ott; Daniel Daley; Erika Fernandez-Vizarra; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Respiratory chain; bc1 complex assembly; mitochondrial protein biogenesis; molecular biology; yeast; Biochemistry; biokemi;

    Abstract : Mitochondria perform a variety of tasks, but the function they are most prominent for is the energy conversion to form ATP, the universal energy equivalent of the cell. The majority of this ATP is created by the oxidative phosphorylation system, consisting of the respiratory chain and the ATP synthase. READ MORE

  5. 3. Structural studies on cytochrome bc1 complex from bovine heart mitochondria

    Author : Momi Iwata; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Ubiquinol:cytochrome c oxidoreductase; membrane protein; X-ray crystallography; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The cytochrome bc1 complex (Ubiquinol:Cytochrome c oxidoreductase or Complex III) is an enzyme of the mitochondrial respiratory chain, crucial for aerobic metabolism. This enzyme catalyses the electron transfer from membrane-bound ubiquinol to soluble cytochrome c. READ MORE

  6. 4. Mechanistic Insights in the Biogenesis and Function of the Respiratory Chain

    Author : Hannah Dawitz; Martin Ott; Cristina Ugalde; Stockholms universitet; []
    Keywords : 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

  7. 5. The mitochondrial processing peptidase-cytochrome bc₁ complex of S. oleracea

    Author : Sara Sjöling; Walter Neupert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Proteins function at distinct sites within the cell, yet most of them are encoded by the nucleus and synthesised in the cytosol. Thus, newly synthesised mitochondrial proteins have to be transported within the cell. READ MORE
