The goal of pE-DB (http://pedb.vib.be) is to serve as an openly accessible database for the deposition of structural ensembles of intrinsically disordered proteins (IDPs) and of denatured proteins based on nuclear magnetic resonance spectroscopy, small-angle X-ray scattering and other data measured in solution. Owing to the inherent flexibility of IDPs, solution techniques are particularly appropriate for characterizing their biophysical properties, and structural ensembles in agreement with these data provide a convenient tool for describing the underlying conformational sampling. Database entries consist of (i) primary experimental data with descriptions of the acquisition methods and algorithms used for the ensemble calculations, and (ii) the structural ensembles consistent with these data, provided as a set of models in a Protein Data Bank format. PE-DB is open for submissions from the community, and is intended as a forum for disseminating the structural ensembles and the methodologies used to generate them. While the need to represent the IDP structures is clear, methods for determining and evaluating the structural ensembles are still evolving. The availability of the pE-DB database is expected to promote the development of new modeling methods and leads to a better understanding of how function arises from disordered states.
pE-DB(http://pedb.vib.be)的目标是作为一个公开可访问的数据库,用于储存基于核磁共振波谱、小角度 X 射线散射和其他溶液中测量数据的结构集合,这些结构集合是无规卷曲蛋白质(IDPs)和变性蛋白质。由于 IDPs 的固有灵活性,溶液技术特别适合于表征它们的生物物理性质,并且与这些数据一致的结构集合为描述潜在的构象采样提供了一个方便的工具。数据库条目包括(i)包含用于集合计算的采集方法和算法描述的原始实验数据,以及(ii)与这些数据一致的结构集合,以 Protein Data Bank 格式提供一组模型。pE-DB 对社区提交开放,并旨在作为传播结构集合及其生成方法的论坛。虽然需要表示 IDP 结构是明确的,但确定和评估结构集合的方法仍在不断发展。pE-DB 数据库的可用性有望促进新建模方法的发展,并导致更好地理解功能如何从无序状态中产生。
