  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. Cytochrome c biogenesis in Bacillus subtilis. Identification and analysis of ccdA

    Author : Torbjörn Schiött; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spore synthesis; haem C; cytochrome c synthesis; Bacillus subtilis; ccdA; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Cytochromes function in electron transfer reactions, e.g. in respiratory systems, and contain haem as a prosthetic group. Cytochromes of the c-type differ from other cytochromes in that haem is covalently attached, via thioether linkages, to two cysteine residues in a conserved sequence motif in the protein, Cys-Xaa-Yaa-Cys-His.

  5. 3. Electron and proton transfer in cytochrome c oxidase

    Author : Magnus Brändén; Peter Rich; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytochrome c oxidase; electron transfer; proton transfer; proton; Biochemistry; Biokemi; biokemi; Biochemistry; Biophysics; biofysik;

    Abstract : This doctoral thesis describes results from studies on the mechanisms by which the enzyme cytochrome c oxidase catalyses the reduction of oxygen to water. Cytochrome c oxidase is the last integral enzyme complex of the socalled respiratory chain in the mitochondrial inner membrane (plasma membrane of bacteria). READ MORE

  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. 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.
