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 in its 2.0 version contains (updated 2014-09-23):
  • RNA sequences and secondary structures, described in dot-bracket notation, derived from the 2430 PDB-deposited RNA structures and their complexes,
  • atom coordinates of the unmodified and modified nucleotide and nucleoside residues (1751600 cases) copied out from the PDB-deposited RNA structures,
  • torsion and pseudotorsion angle values, sugar pucker parameters and complete classification of base pair types given for the PBD-deposited RNA structures.

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