  2. 1. 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

  4. 2. 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

  5. 3. Seismic-Reflection and Seismic-Refraction Imaging of the South Portuguese Zone Fold-and-Thrust Belt

    Author : Cedric Schmelzbach; Christopher Juhlin; Laust Pedersen; Hans Thybo; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Dip-moveout; Prestack time migration; Crooked-line geometry; Traveltime tomography; Inversion; Seismic velocity; IBERSEIS profile; Variscan orogeny; Iberian Pyrite Belt; Geofysik; Earth sciences; Geovetenskap;

    Abstract : The South Portuguese Zone (SPZ), which host world-class massive sulphide deposits, forms the southern fold-and-thrust belt of the Iberian Variscan orogeny. This thesis focuses on seismic-reflection and seismic-refraction processing efforts on a subset of the IBERSEIS deep seismic-reflection data set aiming at resolving the SPZ upper crust in high resolution.
