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

    Author : Frederic Dominique Schramm; Kristina Jonas; Franz Narberhaus; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Coping with Stress : Regulation of the Caulobacter crescentus cell cycle in response to environmental cues

    Author : Kristina Heinrich; Kristina Jonas; Emanuele Biondi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caulobacter crescentus; bacteria; cell cycle; stress; filamentation; cell morphology; DNA replication; cell division; molekylär biovetenskap; Molecular Bioscience;

    Abstract : All organisms have to respond to environmental changes to maintain cellular and genome integrity. In particular, unicellular organisms like bacteria must be able to analyze their surroundings and rapidly adjust their growth mode and cell cycle program in response to environmental changes, such as changes in nutrient availability, temperature, osmolarity, or pH.

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

    Author : Kristen Schroeder; Kristina Jonas; Pierre Genevaux; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Regulated Proteolysis: The Secrets of Lon : Cellular Roles and Stress-dependent Regulation of the Lon Protease

    Author : Matthias J. Fink; Kristina Jonas; Axel Mogk; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lon protease; regulated proteolysis; allosteric regulation; Caulobacter crescentus; stress responses; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Proteolysis is crucial in cells to maintain a functional proteome. It is required for removal of damaged and unfolded proteins during protein quality control, and serves as a mechanism to regulate protein levels through regulated proteolysis. READ MORE

  7. 5. Dicarboxylic acids from xylose, using natural and engineered hosts

    Author : Henrik Almqvist; Avdelningen för kemiteknik; []
    Keywords : Xylose; Dicarboxylic Acids; Biorefineries; Actinobacillus succinogenes; Basfia succiniciproducens; Saccharomyces cerevisiae; Caulobacter crescentus;

    Abstract : Chemical building blocks for plastics can be produced from renewable biomass feedstocks using microbial production organisms, such as yeast or bacteria, in a biorefinery. One class of chemical building blocks that are suitable for production of biobased and biodegradable plastics are dicarboxylic acids, e.g. succinic acid. READ MORE
