A new thermodynamic database for normal and modified nucleic acids has been
developed. This Thermodynamic Database for Nucleic Acids (NTDB) includes s
equence, structure and thermodynamic information as well as experimental me
thods and conditions. In this release, there are 1851 sequences containing
both normal and modified nucleic acids. A user-friendly web-based interface
has been developed to allow data searching under different conditions. Use
ful thermodynamic tools for the study of nucleic acids have been collected
and linked for easy usage. NTDB is available at http:// ntdb.chem.cuhk.edu.
