  1. 1. Studies on Thiol-Disulfide Oxidoreductases in Bacillus subtilis

    Författare :Mirja Carlsson Möller; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Microbiology; bacteriology; bacterial sporulation; endospore; thioredoxin; Thiol-disulfide oxidoreductase;

    Sammanfattning : Bacillus subtilis is a model organism for endospore-forming gram-positive bacteria. Endospores are formed in response to nutrient starvation. They can resist harsh environments and last for long periods of time. Once nutrients again become available, the endospore can germinate and the vegetative life cycle be resumed. LÄS MER

  3. 2. On the role of penicillin-binding protein SpoVD in endospore cortex assembly

    Författare :Ewa Bukowska-Faniband; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sporulation; cortex; Bacillus subtilis; penicillin-binding proteins; SpoVD; peptidoglycan;

    Sammanfattning : Bacteria of the genera Bacillus and Clostridium can form endospores as a strategy to survive unfavourable environmental conditions. Endospore formation involves synthesis of cortex, a thick layer of modified peptidoglycan that surrounds the spore. LÄS MER

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

    Författare :Lydur Erlendsson; Institutionen för experimentell medicinsk vetenskap; []
    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. 4. 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.
