1. Sulphur-Utilizing Microorganisms in Biotechnological Applications - Rubber Recycling and Vanadium Reduction
Abstract : Biotechnological processes offer environmentally friendly and sometimes cost-effective alternatives to traditional chemical and mechanical methods. It is important to take advantages of the opportunities these processes provide to fulfil the demands and expectations of a future environmentally sustainable society. READ MORE

2. Structural and biochemical insights into biosynthesis and degradation of N-glycans
Abstract : Carbohydrates are a primary energy source for all living organisms, but importantly, they also participate in a number of life-sustaining biological processes, e.g. cell signaling and cell-wall synthesis. The first part of the thesis examines glycosyltransferases that play a crucial role in the biosynthesis of N-glycans. READ MORE

3. Single-particle cryo-electron microscopy of macromolecular assemblies
Abstract : In this thesis, single-particle cryo-electron microscopy (cryo-EM) was used to study the structure of three macromolecular assemblies: the two hemocyanin isoforms from Rapana thomasiana, the Pyrococcus furiosus chaperonin, and the ribosome from Escherichia coli. Hemocyanins are large respiratory proteins in arthropods and molluscs. READ MORE

4. Crystallographic studies on redox enzymes containing the thioredoxin fold
Abstract : Three-dimensional structures of two redox enzymes, glutathione peroxidase from human plasma and a protein disulfide oxidoreductase from the archaeon Pyrococcus furiosus, have been determined by X-ray crystallography. Glutathione peroxidases constitute a family of antioxidant seleno-enzymes that catalyze the reduction of a variety of hydroperoxides. READ MORE

5. On the stability of proteins from hyperthermophiles : a structural and thermodynamic study
Abstract : In this study the structural and thermodynamic basis of the thermal stability of proteins has been studied using proteins from hyperthermophilic organisms as model systems. A new type of chaperonin (TF55) has been isolated from the hyperthermophilic archaeon Sulfolobus solfataricus consisting of two different subunits named TF55-alpha and TF55-beta. READ MORE
