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. The sequence of the breakage of disulfide bonds due to x-ray irradiation was observed by time-dependent crystallographic studies of proteins using the strategy we developed for time-dependent structure observations on the atomic scale in a protein crystal for standard crystallography experiments. These observed sequences are related to the reductive unfolding pathways in proteins. ¿he current study focuses on bovine pancreatic ribonuclease A, where the observed breaking sequence is being compared to results by other established methods.

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。二硫键在x射线照射下断裂的顺序是通过蛋白质的时间依赖晶体学研究来观察的，该研究使用了我们开发的用于标准晶体学实验的蛋白质晶体在原子尺度上的时间依赖结构观察策略。这些观察到的序列与蛋白质的还原展开途径有关。目前的研究重点是牛胰腺核糖核酸酶A，其中观察到的断裂序列正在与其他既定方法的结果进行比较。
