Each folder contains the protein-RNA complex, the unbound structure of protein and RNA(wherever available;9 cases).
The transformed coordinates of bound and unbound protein subunits computed by DaliLite and that for RNA subunits computed by Gromacs is also available in the folder.
The subunits have been filtered and only chains of interest are retained in the PDB files.

aFour-letter PDB code of the protein-RNA complexes used in the dataset with the chain ID(s) of the protein and the RNA molecules in the parentheses. Structures solved with NMR spectroscopy method are shown in bold. Symmetry-related chains are primed (e.g. A' in 1j1u).
bSurface area buried between protein and RNA upon complexation.
RMSD was calculated over the cC&alpha atoms of the interface residues, while the values in italics include the phosphorus atoms of the interface nucleotides when the corresponding free RNA structure is available; dAll C&alpha atoms of the protein chain; eAll phosphorus atoms of the RNA chain when the unbound structure of the same is available.
fDifferent categories according to the expected difficulty for the protein-RNA docking algorithm: (R) Rigid body, (S)Semi flexible and (X) Full flexible.
