The Nucleic Acid Knowledgebase (NAKB), portal for 3D structural information about Nucleic Acids, is successor to the Nucleic Acid Database (NDB), as described in:

• Lawson CL, Berman HM, Vallat B, Chen L, Zirbel C (2024) The Nucleic Acid Knowledgebase: a new portal for 3D structural information about nucleic acids. Nucleic Acids Research 52, D245. DOI
• Berman HM, Lawson CL, Schneider B (2022) Developing Community Resources for Nucleic Acid Structures. Life 12, 540. DOI
• November 2023 online lecture (YouTube) describing NAKB to the CASP RNA special interest group.

NAKB provides NA, Protein, and Ligand Annotations, Search, Report, Statistics, Atlas and Visualization for all nucleic-acid containing experimentally determined 3D structures held by NDB and by the Protein Data Bank (PDB), including all major methods: X-ray, Electron Microscopy, and NMR. For each structure, links are provided to external resources that annotate and analyze nucleic acid structures and their complexes.
