This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Radiation damage on protein crystals, especially since data is collected at third generation synchrotron facilities, is an issue and is getting more and more attention. Ultra high resolution structures are what people aspire to obtain. However, ultra high resolution structures are most sensitive to and affected by radiation damage. We applied the new strategy we developed for time-dependent structure observations to remove or minimize radiation effects and thus yield the real high resolution structure from a standard dataset.

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中得到体现。列出的机构是中心的机构，不一定是研究者的机构。蛋白质晶体的辐射损伤是一个问题，特别是因为数据是在第三代同步加速器设施中收集的，并且受到越来越多的关注。超高分辨率结构是人们渴望获得的。然而，超高分辨率结构对辐射损伤最为敏感并受其影响。我们应用了为时间相关结构观测开发的新策略，以消除或最小化辐射效应，从而从标准数据集中产生真正的高分辨率结构。
