Protein crystallography 1. The frontiers of time-resolved macromolecular crystallography: movies and chirped X-ray pulses
Three important frontiers of ultrafast time-resolved macromolecular crystallography are presented: extension of this technique to other biological systems; further developments in the elucidation of mechanism through the analysis of time-dependent movies to extract the underlying, time-independent, intermediate structures; and enhanced time resolution. The last is intimately linked with the nat...

متن کاملThe kinetic dose limit in room-temperature time-resolved macromolecular crystallography
Protein X-ray structures are determined with ionizing radiation that damages the protein at high X-ray doses. As a result, diffraction patterns deteriorate with the increased absorbed dose. Several strategies such as sample freezing or scavenging of X-ray-generated free radicals are currently employed to minimize this damage. However, little is known about how the absorbed X-ray dose affects ti...
متن کاملMacromolecular Crystallography at Chess
CHESS activity report F many years, most synchrotron stations for crystallography, such as CHESS A1, used X-ray sensitive film as the primary detector and xray radiation at about 8 keV (1.5 Å). Two years ago CHESS constructed station F1 on a wiggler line that is tuneable from about 7-14 keV. In practice, this station operates with a standard energy of 0.91 Å. The benefits of using higher energi...
متن کاملStrategies for macromolecular synchrotron crystallography.
Introduction During the past ten years the rate of protein structure determination by X-ray crystallography has risen about tenfold [1]. The use of synchrotron radiation was instrumental for this growth and the fraction of the results obtained this way increased from 28% in 1990 to 80% in 1999 (Figure 1). There are 52 synchrotron stations worldwide used for macromolecular crystallography, and t...
