  2. 11. Active Transport of Ions across Biomembranes : A Kinetic Study of Cytochrome c Oxidase Reconstituted into Phospholipid Vesicles

    Author : Kristina Faxén; Peter Brzezinski; Pia Ädelroth; Thomas E. DeCoursey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; electron transfer; proton transfer; proton pumping; kinetic isotop effect; ion pumping; flow flash; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Ion transport across membranes is of uttermost importance for us. It is the foundation for signaling of various kinds e.g. in the nerve-system. READ MORE

  4. 12. Membrane effects on proton transfer in cytochrome c oxidase

    Author : Linda Näsvik Öjemyr; Peter Brzezinski; Anthony G. Lee; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytochrom c oxidase; lipids; membrane; proton transfer; Biochemistry; biokemi;

    Abstract : The biological membrane is composed of lipids and proteins that make up dynamic barriers around cells and organelles. Membrane-spanning proteins are involved in many key processes in the cell such as energy conversion, nerve conduction and signal transduction. READ MORE

  5. 13. Microcrystallization in lipidic cubic phase and serial crystallography studies of cytochrome c oxidase

    Author : Cecilia Safari; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Serial crystallography; Cytochrome c oxidase; Microcrystallization in lipidic cubic phase;

    Abstract : Life in all living organisms depend on chemical processes performed by proteins, which are molecular machineries encoded in the DNA. Cytochrome c oxidase (CcO) is a membrane protein essential for cellular respiration, a process in which chemical energy enters the electron transport chain in the form of electrons and is transformed to ATP via a proton gradient.

  6. 14. Bacterial Terminal Oxidases. Studies in Bacillus subtilis

    Author : Lena Winstedt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mycology; virology; mykologi; bakteriologi; Mikrobiologi; bacteriology; Microbiology; di-copper center; cytochrome oxidase; Enterococcus faecalis; cytochrome bd; Bacillus subtilis; terminal oxidase; virologi;

    Abstract : The final step in aerobic respiratory pathways is catalyzed by terminal oxidases. Bacteria generally have two or more terminal oxidases. Aerobically grown Bacillus subtilis synthesize three terminal oxidases: one cytochrome c oxidase, cytochrome caa3 and two quinol oxidases, cytochrome aa3 and cytochrome bd. READ MORE

  7. 15. 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 : 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
