NCBI Structure

The Structure database provides three-dimensional structures of macromolecules for a variety of research purposes and allows the user to retrieve structures for specific molecule types as well as structures for genes and proteins of interest. Three main databases comprise Structure-The Molecular Modeling Database; Conserved Domains and Protein Classification; and the BioSystems Database. Structure also links to the PubChem databases to connect biological activity data to the macromolecular structures. Users can locate structural templates for proteins and interactively view structures and sequence data to closely examine sequence-structure relationships.

结构数据库提供了多种研究目的下的大分子三维结构，并允许用户检索特定分子类型的结构，以及感兴趣基因和蛋白质的结构。该数据库主要由三个主要数据库构成：结构-分子建模数据库；保守结构域和蛋白质分类数据库；以及生物系统数据库。结构数据库还与PubChem数据库相链接，以将生物活性数据与宏分子结构相连接。用户可以定位蛋白质的结构模板，并交互式地查看结构和序列数据，以便密切考察序列-结构关系。
