IS RADIATION DAMAGE DEPENDENT ON THE DOSE-RATE USED DURING MACROMOLECULAR CRYSTALLOGRAPHY DATA COLLECTION
OverviewOverview
This paper focuses on the radiation-damage effects when applying the same, total X-ray dose to protein crystals at different dose rates. These, experiments have been performed on both a selenomethionated protein and on, bovine trypsin using dose rates that span nearly two orders of magnitude., The results show no clear dose-rate effect on the global indicators of, radiation damage, but a small measurable dose-rate effect could be found, when studying specific radiation damage. It is hypothesized that this, observed dose-rate effect relates to differences in the steady-state, free-radical concentration.
