NDB核酸晶体结构数据库

**NDB: a repository of experimentally determined 3D structures of nucleic acids** The Nucleic Acid Database (NDB) is a repository of experimentally determined 3D structures of nucleic acids. The structures are determined using X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy. Each structure is accompanied by information about the structure, including the experimental data used to determine the structure, the atomic coordinates, and the structure factors. The NDB is a valuable resource for researchers studying the structure and function of nucleic acids.
