  1. 1. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco

    Författare :Jenny Lindberg; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Abiotic stress; compatible solutes; osmotic stress; osmoprotectants; trehalose; calmodulin; E. coli; N. tabacum; genetic engineering; Biotechnology; Bioteknik; Biochemistry; Metabolism; Biokemi; metabolism; glycine betaine;

    Sammanfattning : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. LÄS MER

  3. 2. Coiled coil cytoskeleton in cell architecture and osmotic stress response in Streptomyces

    Författare :Katsuya Fuchino; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coiled coil protein; Streptomyces coelicolor; polar growth; osmotic-stress response; turgor;

    Sammanfattning : Coiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. LÄS MER

  4. 3. Vitreoscilla Haemoglobin. Genetic Fusions and Metabolic Characterisation

    Författare :Viktoria Roos; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Metabolism; Biokemi; metabolism; osmotic stress; transcript profiling; DNA microarrays; random elongation mutagenesis; directed evolution; mRNA structure; Vitreoscilla haemoglobin VHb ; Escherichia coli; salt stress.;

    Sammanfattning : Vitreoscilla is an obligate aerobic bacterium living in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla expresses a homodimeric haemoglobin (VHb) when subjected to oxygen-limited conditions. LÄS MER

  5. 4. The oxidative and osmotic stress responses of S. cerevisiae

    Författare :Claes Molin; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The yeast Hog1 is a stress responsive mitogen activated protein kinase (MAPK) similar to mammalian p38 and JNK. Rck2 is a protein kinase downstream of Hog1. The Hog1 pathway was previously implicated exclusively in the response to osmotic stress. LÄS MER

  7. 5. Structure and Function of the Borrelia burgdorferi Porins, P13 and P66

    Författare :Mari Bonde; Sven Bergström; Melissa Caimano; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; P13; P66; porin; protein complex; dissemination; osmotic stress;

    Sammanfattning : Borrelia burgdorferi is an elongated and helically shaped bacterium that is the causal agent of the tick-borne illness Lyme disease. The disease manifests with initial flu-like symptoms and, in many cases, the appearance of a skin rash called erythema migrans at the site of the tick bite. LÄS MER
