  •   NMR Refinement Information Hide
    Refinement
    Method simulated annealing, energy minimization
    Details 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. 3',5'-PHOSPHODIESTER LINKAGES BETWEEN RESIDUES, O2' OF EACH RIBOSE MODIFIED BY METHOXYETHYL.
