Hi Ivan,
thanks for replying. Besides the Biophys. J. that you have mentioned,
most recent are
Potential energy surface of the cytosine dimer:
MP2 complete basis set limit interaction energies,
CCSD(T) correction term, and comparison with the AMBER force field
Jurecka P, Sponer J, Hobza P
J. Phys. Chem, B 108, 5466-5471, 2004
Accurate interaction energies of hydrogen-bonded nucleic acid base pairs
Sponer J, Jurecka P, Hobza P
J. Am. Chem. Soc. 126, 10142-10151 2004
Local conformational variations observed in B-DNA crystals do not
improve base stacking: computational analysis of base stacking
in a d(CATGGGCCCATG)(2) B <-> A intermediate crystal structure
Sponer J, Florian J, Ng HL, Sponer JE, Spackova N
Nucl. Acids. Red. 28, 4893-4902 2000
Other methods (CHARMM etc..... were tested in
J. Comput. Chem. 18, 1136-1150, 1997
Hobza et al.
Overall, amber with its RESP charges is very fortunate
and provides very good results for all kinds of neutral
complexes such as base stacking, base pairing, RNA pairing
with O2'H groups, and also for intercalators.
