  2. 11. Time-Resolved and High-Energy Synchrotron Radiation Crystallography using X-ray Area Detectors: Calibration and Applications

    Author : Olof Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis relates to characterisation and calibration techniques for X-ray area detectors with applications in time-resolved and high-energy X-ray crystallography. X-ray crystallography is an interdisciplinary science with important applications in many fields, e.g. chemistry, physics, biology, geology and materials science. READ MORE

  4. 12. Microcrystallization in lipidic cubic phase and serial crystallography studies of cytochrome c oxidase

    Author : Cecilia Safari; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Serial crystallography; Cytochrome c oxidase; Microcrystallization in lipidic cubic phase;

    Abstract : Life in all living organisms depend on chemical processes performed by proteins, which are molecular machineries encoded in the DNA. Cytochrome c oxidase (CcO) is a membrane protein essential for cellular respiration, a process in which chemical energy enters the electron transport chain in the form of electrons and is transformed to ATP via a proton gradient.

  5. 13. Micro-Crystallization and Time-Resolved Diffraction Studies of a Bacterial Photosynthetic Reaction Center

    Author : Petra Båth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Photosynthesis is one of the most important set of chemical reactions in nature as they can convert sunlight into hydrocarbons and chemical energy. The proteins responsible for this are two general types of reaction centers that can be found in a wide variety of living organisms capable of photosynthesis, from bacteria to algae and plants.

  6. 14. Production and Structural Dynamics of Microbial Rhodopsins

    Author : Cecilia Wickstrand; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteriorhodopsin; channelrhodopsin; time-resolved serial femtosecond crystallography;

    Abstract : Rhodopsins are a family of membrane proteins that are found in a wide range of organisms and provide them with the ability to sense and react to light. When light is absorbed by these proteins, structural changes occur that initiate the pumping of protons, opening of a channel or signal transfer. READ MORE

  7. 15. Structural studies of ba3-type cytochrome c oxidase using serial crystallography and X-ray absorption spectroscopy

    Author : Doris Zoric; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ba3-type cytochrome c oxidase; structural biology; X-rays; serial X-ray crystallography; X-ray absorption spectroscopy; enzyme reaction dynamics;

    Abstract : Cytochrome c oxidase (CcO) catalyses the reduction of molecular oxygen to water while the energy released in this process is used transport protons “up-hill” across an energy transducing biological membrane, creating a proton-motive force for ATP synthesis. Given its key role in energy transduction in organisms, proton pumping has been extensively studied across species. READ MORE
