THE nucleic acid modification database (NAMDB) is a database of DNA and RNA modifications that provides comprehensive information concerning the reported modifications occurring in DNA and RNA. The database employs an easy-to-use, searchable interface for obtaining detailed data on the 51 kinds of DNA modifications and 113 kinds of RNA modifications. The NAMDB will be to serve as a primary information portal for researchers across the nucleic acid-related research.

• The chemical structures, common name and symbol, elemental composition and mass of modified 2’-deoxyribonucleosides and ribonucleosides
• The contents of DNA and RNA modifications in a variety of species
• Modifying enzymes for DNA and RNA modifications
• Reference links for the reports of contents and modifying enzymes of DNA and RNA modifications
• Searchable interface for obtaining detailed data of specific modifications.
