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 DNA. 52 structures, i. e. Dimethylphosphate (conformation gauche, gauche; 4 mol. orientations) and the 4 DNA nucleosides [Deoxyadenosine, Deoxycytidine, Deoxyguanosine and Deoxythymidine (conformations C2'endo and C3'endo; 6 mol. orientations for each conformation) 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-46, F-47, F-48, F-49 and F50 and compatible with the project F-51 (RNA force field topology database). The difference between the projects F-45 and F-50 is that the phosphate group is located at the position O5' and O3', respectively.
