  1. 6. Heme A synthase from Bacillus subtilis and Aeropyrum pernix

    Författare :Anna Lewin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heme A synthesis; heme A; heme A synthase; CtaA; cCtaA; cytochrome a; Aeropyrum pernix; Bacillus subtilis;

    Sammanfattning : Respiration in animals, plants and many bacteria is dependent on heme A, which functions as a prosthetic group in a-type cytochromes (terminal energy-transducing oxidases in the electron transport chain that reduce molecular oxygen to water). Heme A synthase catalyses a chemically very demanding reaction, the conversion of one specific methyl side-group of heme O to a formyl group of heme A. LÄS MER

  3. 7. The Bacillus subtilis GlpP protein, antitermination and mRNA stability

    Författare :Elisabeth Glatz; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; leader sequence; glpD; GlpP; catabolite repression; mRNA stability; Bacillus subtilis; antiterminator protein; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Bacillus subtilis can grow on glycerol or glycerol-3-phosphate (G3P) as the sole carbon and energy source. The glpD gene encodes G3P dehydrogenase which is required for the catabolism of glycerol and G3P. LÄS MER

  4. 8. Tetrapyrrole synthesis in Bacillus subtilis

    Författare :Mats Hansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes tetrapyrrole synthesis in the aerobic Gram positive bacterium Bacillus sub-tilis. Tetrapyrroles such as heme of a-, b-, c-, d- and o-type can be synthesised in this organism. In addition, there is strong evidence for the presence of the tetrapyrrole siroheme in B. subtilis.

  5. 9. Heterogeneous electron transfer studies with ligninolytic redox enzymes and living bacteria. Applications in biosensors and biofuel cells

    Författare :Vasile Coman; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; mediated electron transfer; self-assembled monolayer; flow injection analysis; amperometric biosensor; E. coli; succinate:quinone reductase; biofuel cell; B. subtilis; whole-cell biosensor;

    Sammanfattning : The catalytic properties and the inter-domain electron transfer of cellobiose dehydrogenase (CDH) from the ascomycete fungus Myriococcum thermophilum adsorbed on graphite and thiol (SAM) modified gold electrodes were investigated using cyclic voltammetry, flow injection amperometry and UV-Vis spectroelectrochemistry. The fabrication and characterisation of a noncompartmentalised, mediator and cofactor free glucose–oxygen biofuel cell well-operating in glucose-containing buffers and human blood serum was performed.

  7. 10. 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.
