Protein NMR is a powerful tool for studying protein structure, dynamics and interactions at atomic resolution. However, currently it is time-consuming and laborious to obtain NMR resonance assignment and the NMR structure of a protein. Here we will leverage recent advances in Euclidean distance geometry to develop a method for simultaneous determination of resonance assignment and protein structure using only the NOESY spectra. We have two aims: 1. Method development and validation using synthetic data based on known protein structure; 2 Method development and validation using experimental NMR data.

蛋白质核磁共振是研究蛋白质结构、动力学和相互作用的有力工具 原子分辨率。然而，目前获取核磁共振是费时费力的 蛋白质的共振归属和核磁共振结构。在这里，我们将利用最近 欧几里德距离几何的进展为联立计算提供了一种方法 仅使用NOESY光谱确定共振归属和蛋白质结构。 我们有两个目标：1.基于合成数据的方法开发和验证 已知的蛋白质结构；2使用实验核磁共振的方法开发和验证 数据。
