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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Visualizing structural dynamics: from small molecules to membrane proteins

    Författare :Magnus Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane protein; bacteriorhodopsin; proteorhodopsin; halorhodopsin; structural dynamics; time-resolved X-ray scattering;

    Sammanfattning : To fully understand the mechanism of a chemical reaction, it is important to characterize the rapid structural dynamics of transient chemical species as the reaction propagates. Since chemical processes are heavily influenced by the solvent in which they occur, the interaction with the surrounding solution also needs to be elucidated. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
