2. 1. Unravelling protein stability and aggregation

   Author : Tanja Weiffert; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein aggregation; amyloid beta peptide; protein stabilization; split GFP; monellin; secretagogin; ; aggregation kinetics; toxicity; aggregation mechanism; coaggregation;

   Abstract : Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. READ MORE

4. 2. Spectroelectrochemistry of Redox Enzymes

   Author : Andreas Christenson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; complex II; bilirubin oxidase; laccase; enzyme mechanism; redox potential; electron transfer; spectroelectrochemistry; redox enzymes; Spectroelectrochemical cell;

   Abstract : A low volume and long optical path spectroelectrochemical cell was constructed and tested in a number of applications such as detection of direct electron transfer (DET) between redox enzymes and gold electrodes, determination of the formal potentials of redox centres in proteins and enzymes, as well as mechanistic studies of heterogeneous and intermolecular electron transfer of copper oxidases and succinate:quinine oxidoreductase (Complex II). The existence of DET between enzymes and electrodes was demonstrated for theophylline oxidase, cytochrome P450 cam, laccase, bilirubin oxidase, sulphite oxidase and Complex II. READ MORE

5. 3. Nitrogen and Redox Metabolism in Saccharomyces cerevisiae

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

7. 5. Engineering of Human Fetal Hemoglobin

   Author : Karin Kettisen; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fetal hemoglobin; protein engineering; recombinant protein production; protein purification; chromatography; oxygen carrier; redox reactions; net surface charge; DNA cleavage;

   Abstract : In blood, the oxygen-transporting protein hemoglobin (Hb) governs the oxygenation of cells and tissues. Naturally, this protein has claimed a place in the center of the research field of artificial oxygen therapeutics. READ MORE
