Stacking of aromatic amino acids tryptophan (Trp), tyrosine (Tyr), phenylalanine (Phe), and histidine (His) with bases and base pairs of nucleic acids has been studied. Stacking energies of the amino acid-base (or base pair) complexes have been calculated by second-order perturbation theory. Our res

## Abstract In building and refining nucleic acid structures, it is often desirable to enforce particular base pairing and/or base stacking interactions. Energy‐based modeling programs with classical molecular mechanics force fields do not lend themselves to the easy imposition of penalty terms cor
The results of systematic ab initio calculations of 15 N and 1 H chemical shielding tensors in the GC base pair as a function of hydrogen bond length are presented for the first time. The hydrogen bond length characterized by the distance r N. . .N between purine N1 and pyrimidine N3 was varied betw
