6. Generation and exploitation of proton motive force: Biochemical and structural analysis of three bacterial integral membrane proteins
Abstract : Proton motive force, a necessity for all living cells, is generated and exploited by asignificant number of membrane-bound enzymes and transporters. The focus of thisthesis was to understand the physiological relevance, structure and mechanism of threesuch bacterial enzymes: proteorhodopsin; transhydrogenase; and AcrB. READ MORE

7. On the crystallization of membrane proteins in lipidic sponge and cubic phases
Abstract : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. READ MORE

8. Housing Aquaporins in Nanostructured Glass
Abstract : Proteins are a group of biomolecules that perform versatile tasks, which in many cases are essential for life. The magnitude of their importance is perhaps expressed by the word protein itself, coined by the Swedish chemist Jöns Jacob Berzelius in the summer of 1838. READ MORE

9. Calculations of Reaction Mechanisms and Entropic Effects in Enzyme Catalysis
Abstract : Ground state destabilization is a hypothesis to explain enzyme catalysis. The most popular interpretation of it is the entropic effect, which states that enzymes accelerate biochemical reactions by bringing the reactants to a favorable position and orientation and the entropy cost of this is compensated by enthalpy of binding.

10. Light’EM up! : structural characterization of light-driven membrane protein complexes by cryogenic electron microscopy
Abstract : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. READ MORE
