Abstract

RESP atomic charges for the four nucleosides of DNA, i. e. Deoxyadenosine, Deoxycytidine, Deoxyguanosine and Deoxythymidine (conformations C2'endo and C3'endo) based on the Connolly surface algorithm and the HF/6-31G* theory level. Charges suitable for MD simulations using the Cornell et al. AMBER force field (and/or its adaptations). Charges derived using 2 mol. conformations and 6 mol. orientations (Rigid-Body Reorientation Algorithm) for each conformation. Charge values to be compared with those reported in the projects W-70, W-71, W-72 and W-73 and compatible with the project W-74 (RNA nucleosides).
