Structural Patterns and Stabilities of Hydrogen-Bonded Pairs Involving Ribonucleotide Bases and Arginine, Glutamic Acid, or Glutamine Residues of Proteins from Quantum Mechanical Calculations.

More importantly, the difference in interaction energies between each type of multimodal structure is smaller in the solvent phase compared to the gas phase. This points toward the possibility of switching between such structurally similar and energetically close interaction states, which may be significant for the dynamics at the RNA:protein interface.
