  2. 1. Energy Transduction and Sensory Signalling in Haloarchaea Structural Characterisation of the Photocycles of Bacteriorhodopsin and Sensory Rhodopsin II

    Author : Karl Edman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic crystallography; proton pumping; Haloarchaea; structural mechanism; bacteriorhodopsin; sensory signalling; sensory rhodopsinII; retinal proteins;

    Abstract : Archaeal rhodopsins belong a subfamily of heptahelical transmembrane proteins. All contain a buried retinal chromophore covalently bound to a conserved lysine residue in helix G via a protonated Schiff base. READ MORE

  4. 2. 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

  5. 3. Time-resolved X-ray diffraction and solution scattering studies of Sensory Rhodopsin II in isolation and in complex with its transducer

    Author : Giorgia Ortolani; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; light-activated membrane protein; microbial Rhodopsins; Sensory rhodopsin II; SRII; SRII:HtrII; transducer; SSX; XSS; time-resolved;

    Abstract : Light is an important source of energy for many living organisms. Many life forms have therefore evolved cellular receptors that are able to sense light and thereby optimise conditions for photosynthesis and pho- totrophy. READ MORE

  6. 4. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses

    Author : Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; GPCRs; G proteins; Sensory system; Signal transduction; Olfaction; Chemosensation; Hemichordates; Sponges; Porifera; Bilaterians; Holozoans; Fungi; Opisthokonts; Bioinformatics; Bioinformatik;

    Abstract : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. READ MORE

  7. 5. Lipidic Cubic Phase Microcrystallization and its Application in Serial Crystallography

    Author : Rebecka Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structural biology; Lipidic Cubic Phase; Cytochrome c oxidase; Serial Crystallography;

    Abstract : Every living organism contain a cell membrane which is an important cell structure with a vast variety of different functions such as cell signaling, transportation and energy production. One of the most important functions is to produce energy for the cell to thrive. READ MORE
