aFour-letter PDB code of the protein-RNA complexes with the chain ID(s) of the protein and the RNA molecules in the parentheses. Symmetry-related chains are primed (e.g., FF' in1SDS).

bSurface area buried between protein and RNA upon complexation.

crmsd calculated considering the equivalent Cα atoms.

drmsd calculated considering the equivalent phosphorus (P) atoms.

ermsd calculated considering the equivalent interface atoms.

fClassification of different categories: Rigid [R], Semi-flexible [S] Full-flexible [F].

gBinding affinity values taken from literature.

hAbsolute temperature at which affinity is measured.

ipH at which affinity is measured.

jGibbs free energy of association calculated from ΔG = RTlnKd , where R is the gas constant and T is the absolute temperature.

kExperimental methods used for the determination of Kd :

Filtration assay or Filter binding assay (FBA), Fluorescence titration (FT), Electrophoretic mobility shift assay (EMSA), Binding kinetics (KB), Isothermal titration calorimetry (ITC),\ Surface plasma resonance (SPR), Fluorescence polarization (FP), Microscale thermophoresis (MST), TSR Methyltransferase Assay (TSR) and Dot Blot RNA-Binding Assays (Dot blot).

lPubMed accession ID of literature.

†Complexes for which only single chain is available in the unbound forms. The bound PDB chain used for superposition with unbound PDB chain is underlined in bold font. (e.g. 2OZB AB:C)
