  1. 1. Redox Regulation and Stress Responses - Studies in Bacillus subtilis

    Författare :Jonas Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox sensor; oxygen sensor; reactive nitrogen species; RNS; Biology; Biologi; Microbiology; bacteriology; virology; mycology; bakteriologi; Mikrobiologi; virologi; mykologi; Bacillus subtilis; Rex; yjbI; ydiH; yjbH; redox regulation;

    Sammanfattning : Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. LÄS MER

  3. 2. Regulation of photosynthesis -Cytochrome b6f in redox regulation -Two novel proteases acting on an N-terminal peptide of LHCII

    Författare :Jörgen Ström; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; Växtbiokemi; cGEP; proteolysis; protease; protein phosphorylation; redox regulation; light-harvesting antenna; cytochrome b6f; chloroplast; Photosynthesis;

    Sammanfattning : In higher plants photosynthesis takes place in the chloroplast. This work focuses on two different processes that effects photosynthesis. Firstly, we studied the events occurring prior to the phosphorylation of LHCII. Secondly, we also studied two novel proteases, with the potential to degrade LHCII. LÄS MER

  4. 3. Nitrogen and Redox Metabolism in Saccharomyces cerevisiae

    Författare :Eva Albers; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces cerevisiae; glutamate; protein expression; anaerobic physiology; nitrogen metabolism; redox; serine;

    Sammanfattning : Anaerobic conversion of glucose to ethanol by the yeast Saccharomyces cerevisiae has been studied. Glycerol is formed as a by-product in order to maintain the overall redox balance. LÄS MER

  5. 4. Systems biology techniques show high prevalence of post-translational regulation in the cyanobacterium Synechocystis PCC 6803

    Författare :Jan Karlsen; Elton Paul Hudson; Martin Hagemann; KTH; []
    Nyckelord :systems biology; sustainable development; omics; ribosome profiling; RNA sequencing; proteomics; genetic engineering; bioproduction; cyanobacteria; gene regulation; metabolism; translational regulation; post-translational regulation; bioinformatics; Bioteknologi; Biotechnology;

    Sammanfattning : Earth's climate has been upset by carbon dioxide (CO2) emissions from human activities and the use of fossil resources. To prevent catastrophic events on the environment and on civilizations, we urgently need to develop alternative solutions that utilize renewable resources. LÄS MER

  7. 5. Signalling in plant mitochondria. Redox regulation of gene expression & characterisation of a pea nucleoside diphosphate kinase

    Författare :Martha L Escobar Galvis; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mitochondrial gene expression; redox; respiratory complex II; NDPK; protein interactions; heat-stress; Växtbiokemi; Plant biochemistry;

    Sammanfattning : This work contributes to our understanding of mitochondrial responses to changing environmental conditions in plants. The first part of this thesis is focused in the study of redox regulation of mitochondrial gene expression. By using inhibitors, the redox state of the components of the mitochondrial respiratory chain was selectively affected. LÄS MER
