simulated annealing, energy minimization
structures were refined by NMR restrained molecular dynamics in two stages using a generalized born (GB) implicit solvation model. The resulting structures were subjected to energy minimization.
2',5' phosphodiester linkages between residues, O3* of each ribose modified by methoxyethyl.
