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

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

    Sammanfattning : 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.

  2. 2. Structure and Function of Cytochrome c Oxidase

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

    Sammanfattning : 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. LÄS MER

  3. 3. Studies on Haemproteins of Gram-positive Bacteria - Implications as Antibacterial Drug Targets

    Författare :Peter Kjelgaard; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteriology; virology; mycology; Mikrobiologi; Microbiology; heme; Truncated hemoglobins; cytochrome c maturation; cytochrome bd; ResB; bakteriologi; virologi; mykologi;

    Sammanfattning : With the discovery of antibiotics, several diseases that were previously lethal is today readily cured, or so we thought. Some degree of resistance to one or several antibiotics can be found among many strains of clinical important bacteria. LÄS MER

  4. 4. Biogenesis and assembly of the mammalian mitochondrial inner membrane

    Författare :Antek Wielburski; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aims of this investigation were to study the synthesis and assembly of mammalian mitochondrial inner membrane with emphasis on cytochrome c oxidase. Model systems utilizing rat hepatocytes and digitonin-treated hepatocytes were established for use in the investigation of mitochondrial protein synthesis in mammalian cells. LÄS MER

  5. 5. 2nd and 3rd generation electrodes for biosensors and biofuel cells

    Författare :MNadeem Zafar; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Sammanfattning : The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER
