2. 1. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin

   Author : Robert Bosman; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rhodopsin; SRII; SRII-HtrII; Time-resolved crystallography; Time-resolved wide angle x-ray scattering; TR-X; TR-WAXS; Serial crystallography;

   Abstract : Responding to different light conditions is an essential process for many organisms on earth. Unicellular organisms are no exception to this and mechanisms for controlling cellular movement must often be sensitive to light. READ MORE

4. 2. Implementation and development of serial synchrotron crystallography at MAX IV

   Author : Bjelčić Monika; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ssx; time-resolved; crystallography; MAX IV LAboratory;

   Abstract : Over the past decade, remarkable advancements in femtosecond X-ray free-electron lasers (XFELs) have brought about a profound transformation in structural biology. These XFELs have opened up exciting opportunities for conducting high-time resolution, room-temperature studies on protein structures and dynamics. READ MORE

5. 3. Advances in Membrane Protein Structural Biology: Lipidic Sponge Phase Crystallization, Time-Resolved Laue Diffraction and Serial Femtosecond Crystallography

   Author : Linda C Johansson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Serial femtosecond crystallography; Lipidic sponge phase crystallization; Membrane protein crystallization; X-ray free-electron laser;

   Abstract : Membrane proteins carry out many essential tasks in cells such as signaling and transport, or function as electron carriers in photosynthesis and cellular respiration. The aim of this thesis has been to develop new and improve existing techniques for elucidating the structure and function of membrane proteins. READ MORE

6. 4. 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. 5. 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
