  2. 1. 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

  4. 2. Characterization of ATP-dependent protein dynamics under native-like conditions

    Author : Harsha Ravishankar; Magnus Andersson; Hans Wolf-Watz; Lise Arleth; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; structural dynamics; ATPases; MD simulations; X-ray scattering; FTIR spectroscopy; ATP; TR-XSS; structural biology.; Biochemistry; biokemi;

    Abstract : Proteins are biological macromolecules capable of accelerating biochemical reactions. To accomplish this, proteins undergo changes in their molecular structure. Advances in structural biology have resulted in ever-increasing numbers of high-resolution protein structures. READ MORE

  5. 3. Escape from the cage: Ultrafast structural dynamics of photodissociation reactions observed with X-ray solution scattering

    Author : Amke Nimmrich; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The environment of a molecule is known to greatly impact the course of a reaction. Such an environment can, for instance, be the solvent in a solution phase reaction or the amino acid residues surrounding a chromophore in photoreceptor proteins. READ MORE

  6. 4. Determining the effects of regulatory parameters on the structural dynamics of P-type ATPase membrane transporters

    Author : Fredrik Orädd; Magnus Andersson; Magnus Wolf-Watz; Marco Cammarata; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein dynamics; regulation; time-resolved x-ray solution scattering; MD simulation; membrane protein; P-type ATPase; SERCA; CopA; HMA4; adenylate kinase; Physical Chemistry; fysikalisk kemi;

    Abstract : Proteins are macromolecular machines with roles in all cellular activities and structures. The functional properties of each protein is the result of its combination of 3D-structure and inherent dynamics, and a wealth of structural and dynamic mechanisms have evolved to regulate protein activity.

  7. 5. 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
