  1. 1. Bacterial Terminal Oxidases. Studies in Bacillus subtilis

    Detta är en avhandling från Lena Winstedt, Department of cell and organism biology, Sölvegatan 12, S-223 62 Lund, Sweden

    Författare :Lena Winstedt; Lund University.; Lunds universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mycology; virology; mykologi; bakteriologi; Mikrobiologi; bacteriology; Microbiology; di-copper center; cytochrome oxidase; Enterococcus faecalis; cytochrome bd; Bacillus subtilis; terminal oxidase; virologi;

    Sammanfattning : 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. LÄS MER

  2. 2. Prokaryotic Arsenic Resistance - Studies in Bacillus subtilis

    Detta är en avhandling från Lena Winstedt, Department of cell and organism biology, Sölvegatan 12, S-223 62 Lund, Sweden

    Författare :Emil Aaltonen; Lund University.; Lunds universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ArsB; Bacillus subtilis; arsenic resistance; arsenate reduction; arsenite transport; gene regulation; arsenate; ArsR; arsenite; transmembrane topology; Acr3; ArsK;

    Sammanfattning : Arsenic is a toxic metalloid which is found all over the globe. Due to its toxicity and wide abundance, all living organisms have evolved intrinsic arsenic resistance systems. In this study, three proteins that provide arsenic resistance in the Gram-positive bacterium Bacillus subtilis have been investigated. LÄS MER

  3. 3. Stability determinants and decay of Bacillus subtilis mRNAs

    Detta är en avhandling från Department of Cell and Organism Biology, Lund University

    Författare :Gustav Hambraeus; Lund University.; Lunds universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; Microbiology; Bacillus subtilis; mRNA stability; degradation;

    Sammanfattning : Degradation of mRNA is a controlled process which is as important for gene regulation as the synthesis of mRNA. This thesis focuses on mechanisms of mRNA stability and degradation in Bacillus subtilis, the model of Gram-positive bacteria. LÄS MER

  4. 4. Membrane-bound thiol-disulfide oxidoreductases in Bacillus subtilis

    Detta är en avhandling från Lydur Erlendsson, Department of cell and organsimbiology, Sölvegatan 35, Lund

    Författare :Lydur Erlendsson; Lund University.; Lunds universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virologi; mykologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; sporulation; cytochrome c; thiol-disulfide oxidoreductases; Bacillus subtilis; membrane proteins; bakteriologi;

    Sammanfattning : Disulfide bonds in proteins are found between cysteine residues and are usually important for either function or stability of proteins. Thiol-disulfide oxidoreductases catalyse the formation or breakage of disulfide bonds in proteins. LÄS MER

  5. 5. Redox Regulation and Stress Responses - Studies in Bacillus subtilis

    Detta är en avhandling från Cell and Organism Biology Lund University Sölvegatan 35 SE-22362 Lund

    Författare :Jonas Larsson; Lund University.; Lunds universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox sensor; oxygen sensor; reactive nitrogen species; RNS; Biology; Biologi; Microbiology; bacteriology; virology; mycology; bakteriologi; Mikrobiologi; virologi; mykologi; Bacillus subtilis; Rex; yjbI; ydiH; yjbH; redox regulation;

    Sammanfattning : Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. LÄS MER
