  1. 1. 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

  3. 2. 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

  4. 3. Streptomyces sporulation - Genes and regulators involved in bacterial cell differentiation

    Författare :Jessica Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streptomyces coelicolor; venezuelae; morphological differentiation; WhiH; WhiA;

    Sammanfattning : Streptomycetes are Gram-positive bacteria with a complex developmental life cycle. They form spores on specialized cells called aerial hyphae, and this sporulation involves alterations in growth, morphogenesis and cell cycle processes like cell division and chromosome segregation.

  5. 4. 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

  7. 5. The Saccharomyces cerevisiae MAPKAP kinases Rck1 and Rck2 in stress responses

    Författare :Elizabeth Bilsland; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Saccharomyces cerevisiae protein kinases Rck1 and Rck2 (Radiation sensitivity Complementing Kinases) were originally cloned as suppressors of Schizosaccharomyces pombe checkpoint mutants. In Saccharomyces cerevisiae we found that overexpression of either kinase has the ability to depress sporulation in mec1 and rad24 mutant backgrounds. LÄS MER
