  2. 1. Molecular machinery of a membrane-bound proton pump : Studies of charge transfer reactions in cytochrome c oxidase

    Author : Emelie Svahn; Peter Brzezinski; Ville Kaila; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane protein; respiration; redox reaction; cytochrome aa3; cytochrome c oxidase; Biochemistry; biokemi;

    Abstract : In cellular respiration, electron transfer from the breakdown of foodstuff is coupled to the formation of an electrochemical proton gradient. This is accomplished through proton translocation by respiratory complexes, and the proton gradient is subsequently used e.g. to drive ATP production. READ MORE

  4. 2. 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

  5. 3. Synthesis of hemes found in heme-copper oxidases of Bacillus subtilis

    Author : Mimmi Throne-Holst; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Biologi; Biology; heme biosynthesis; respiratory oxidase; cytochrome; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The last step of aerobic respiration, the reduction of dioxygen to water, is catalysed by terminal oxidases. These oxidases can be divided into two unrelated families, the heme-copper oxidases and the cytochrome bd-type oxidases. These enzymes contain two or more heme molecules as prosthetic groups.

  6. 4. 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

  7. 5. 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.
