The Worldwide Protein Data Bank manages the public archive of 3D structures for proteins, nucleic acids, and complex assemblies.
Nucleic Acid Knowledgebase
The Nucleic Acid Knowledgebase provides 3D structural information about nucleic acids, with structures, search, and full-text access.
About Nucleic Acid Knowledgebase
NAKB is a portal for 3D structural information about nucleic acids. It is the successor to the Nucleic Acid Database and covers nucleic-acid-containing, experimentally determined structures held by NDB and the Protein Data Bank, including structures solved by X-ray, electron microscopy and NMR.
It provides annotations for nucleic acids, proteins and ligands, along with search, reports, statistics, an Atlas and visualization. For each structure, it links to external resources that annotate or analyze nucleic acid structures and complexes. The site is web-based, and its pricing is not stated.
