  2. 1. Genes for cytochrome c and cytochrome c oxidase synthesis in Bacillus subtilis

    Author : Jenny Bengtsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; cytochrome; cytochrome c oxidase; Bacillus subtilis; cytochrome c synthesis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Cytochromes are heme-containing proteins that function in electron transfer reactions, e.g. respiration and photosynthesis. There are several different types of cytochromes. READ MORE

  4. 2. 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 : 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

  5. 3. Structural elements involved in protein-mediated proton transfer : Implications from studies of cytochrome c oxidase

    Author : Ann-Louise Johansson; Martin Högbom; Peter Brzezinski; Bertrand García-Moreno; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; proton transfer; Biochemistry; biokemi;

    Abstract : Proton transfer is one of the most common reactions in biological systems. During energy conversion inside a cell, proton transfer is crucial to maintain an electrochemical proton gradient across the cell membrane. This gradient is in turn used to e.g. READ MORE

  6. 4. Structure and Function of Cytochrome c Oxidase

    Author : Gisela Brändén; Peter Brzezinski; Mårten Wikström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; proton pumping; proton transfer; electron transfer; X-ray crystallography; flow flash; Biochemistry; Biokemi;

    Abstract : Aerobic organisms, ranging from bacteria to humans, obtain their energy through the process of respiration. Electrons from the breakdown of food are transported through the membrane-bound enzyme complexes of the respiratory chain, to the terminal acceptor molecule, oxygen. READ MORE

  7. 5. Choreography of a proton pump : Studies of charge-transfer reactions in cytochrome c oxidase

    Author : Jóhanna Vilhjálmsdóttir; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; respiration; proton pump; electron transfer; proton transfer; proton-transfer pathway; midpoint potential; proton-pumping mechanism; Biochemistry; biokemi;

    Abstract : In the last step of cellular respiration, electrons from metabolites are transferred to molecular oxygen, mediated by the enzyme complexes of the respiratory chain. Some of these enzyme complexes couple these redox reactions to formation of an electrochemical proton gradient across the cell membrane. The proton gradient is used e.g. READ MORE
