  1. 1. Stress response regulation and protein aggregate inheritance in Caulobacter crescentus

    Författare :Frederic Dominique Schramm; Kristina Jonas; Franz Narberhaus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stress; protein aggregation; cellular aging; molecular chaperones; heat shock response; DnaK; sigma factor; suppressor genes; DNA replication; starvation; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Many stress conditions a cell encounters threaten the continuation of basic biological processes ultimately endangering its survival. Heat shock and antibiotic exposure can lead to a sudden surge of protein un- and misfolding, while nutrient starvation directly causes a lack of energy and molecular building blocks. LÄS MER

  3. 2. Proteostasis in Bacillus subtilis : chaperones and stress-response mechanisms

    Författare :Judith Matavacas; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein homeostasis; Chaperones; DnaK; trigger factor; Spx; YjbH; Bacillus subtilis;

    Sammanfattning : The maintenance of protein homeostasis, also referred to as proteostasis, is essential for preserving the structural and functional stability of the proteome in living organisms. This involves the precise control of protein synthesis, folding, and degradation. LÄS MER

  5. 4. Caulobacter crescentus folding machines at the interface of inheritance, cell division, and energy metabolism

    Författare :Kristen Schroeder; Kristina Jonas; Pierre Genevaux; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chaperones; DnaK; chaperonin; GroESL; protein quality control; protein folding; stress response; cellular aging; cell division; bacterial respiration; Caulobacter crescentus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : All living cells must perform essential biological processes while monitoring and responding to environmental cues. Bacteria are accessible experimental systems in which to study the function of conserved central processes. LÄS MER

  7. 5. Morphological changes in mycobacteria

    Författare :Malavika Ramesh; Leif A. Kirsebom; Anders Løbner-Olesen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mycobacteria; pleomorphism; dnaK_3; microaerobic condition; Morphology; oxygen deprivation; spore-like cells; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : Morphological variations at different stages and conditions of growth has been observed frequently in various mycobacteria. Despite years of research, the molecular basis of such variations is still not clear and requires further elucidation. LÄS MER
