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
The crystal structure of d(CATGGGCCCATG)(2) shows unique stacking patterns of a stable B↔A-DNA intermediate. We evaluated intrinsic base stacking energies in this crystal structure using an ab initio quantum mechanical method. We found that all crystal base pair steps have stacking energies close to...
