: 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
- RNA sequences and secondary structures, described in dot-bracket notation,
derived from the 2579 PDB-deposited RNA structures and their complexes,
- atom coordinates of the unmodified and modified nucleotide and nucleoside residues (1860612 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.
