Laue Crystallography: It's show time
New crystallographic techniques make it possible to observe directly all of the intermediates in an enzymatic reaction. Such a series of structures can be combined to create a detailed movie of enzymatic catalysis.
متن کاملLaue crystallography: Lights! Camera! Action!
Recent advances in the Laue method of X-ray data collection from protein crystals have allowed very short-lived reaction intermediates to be observed successfully.
متن کاملThe RATIO method for time-resolved Laue crystallography.
A RATIO method for analysis of intensity changes in time-resolved pump-probe Laue diffraction experiments is described. The method eliminates the need for scaling the data with a wavelength curve representing the spectral distribution of the source and removes the effect of possible anisotropic absorption. It does not require relative scaling of series of frames and removes errors due to all bu...
متن کاملWatching a signaling protein function in real time via 100-ps time-resolved Laue crystallography.
To understand how signaling proteins function, it is crucial to know the time-ordered sequence of events that lead to the signaling state. We recently developed on the BioCARS 14-IDB beamline at the Advanced Photon Source the infrastructure required to characterize structural changes in protein crystals with near-atomic spatial resolution and 150-ps time resolution, and have used this capabilit...
متن کاملNew methods in time-resolved Laue pump–probe crystallography at synchrotron sources
Newly developed methods for time-resolved studies using the polychromatic and in particular the pink-Laue technique, suitable for medium and small-size unit cells typical in chemical crystallography, are reviewed. The order of the sections follows that of a typical study, starting with a description of the pink-Laue technique, followed by the strategy of data collection for analysis with the RA...
