  2. 16. Microcrystallization and structural studies of proteins by serial crystallography and x-ray scattering

    Author : Owens Uwangue; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Proteins are the most complex and versatile biomolecules known, with essential roles in all cellular and physiological processes. They constitute the main structural components of cells, catalyze most biochemical reactions, regulate gene expression, modulate immune responses, and form tissues. READ MORE

  4. 17. X-ray - Based Studies of Structural Dynamics in Solids and Liquids

    Author : Ralf Nüske; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The wavelength of x-ray radiation is much shorter than that of visible light. In fact, it is comparable to the distances between atoms in solids, which is on the order of one tenth of a nanometer. Using light of such a short wavelength, it is possible to study the structure of materials on the atom level. READ MORE

  5. 18. Visualizing structural dynamics: from small molecules to membrane proteins

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

    Abstract : 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. READ MORE

  6. 19. Detecting and Identifying Solution-structural Change in Photoactive Proteins

    Author : Alexander Björling; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein dynamics; X-ray scattering; Light sensing proteins;

    Abstract : Conformational dynamics allow proteins to fulfil their biological roles, yet the understanding of these molecular machines is largely limited to structural snapshots. Time-resolved X-ray scattering provides a possible way of uncovering such dynamics, but hinges on the ability to trigger reactions, and most critically on the ability to interpret the resulting data.

  7. 20. 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
