Dear users,
recently we have released RNA FRABASE version 2.0!

In the near future both versions of the tool will be open. However, the RNA FRABASE 1.0 database is no longer updated.


RNA FRABASE: an engine with database to search the three-dimensional fragments within 3D RNA structures using as an input the sequence(s) and / or secondary structure(s) given in the dot-bracket notation.

Database contains (updated 2009-12-12):
  • RNA sequences and secondary structures, described in dot-bracket notation, derived from the 1400 PDB-deposited RNA structures and their complexes,
  • atom coordinates of the unmodified and modified nucleotide and nucleoside residues (621437 cases) copied out from the PDB-deposited RNA structures,
  • torsion angle values, sugar pucker parameters and classification of base pair types given for the PBD-deposited RNA structures.

Sequence(s) and / or secondary structure(s):
