Abstract

RESP atomic charges based on the Connolly surface algorithm and the HF/6-31G* theory level for the 16 components of a force field topology database useful for modeling regular RNA. 28 structures, i. e. Dimethylphosphate (conformation gauche, gauche; 4 mol. orientations) and the 4 RNA nucleosides [Adenosine, Cytidine, Guanosine and Uridine (conformation C3'endo, dihedral constraints were used in the geometry optimization step to avoid intra-molecular hydrogen bonds and transition state type structures: HO3'-O3'-C3'-C4' = 180 deg., HO2'-O2'-C2'-C3' = 290 deg.; 6 mol. orientations) are used in the charge derivation. Procedure automatically carried out using the R.E.D.-III program (mol. orientation controlled using the rigid-body re-orientation algorithm implemented in R.E.D.). Charges are similar that those calculated in the Cornell et al. AMBER force field (and/or its adaptations, see Cieplak et al. J. Comput. Chem. 1995, 16, 1357-1377) althought these new values present the advantage to be highly reproducible. Charge values to be compared with those reported in the projects F-51, F-52, F-53, F-54 and F55 and compatible with the project F-50 (DNA force field topology database). The difference between the projects F-56 and F-51 is that the phosphate group is located at the position O3' and O5', respectively.
