Table 2. Root-Mean-Square Deviations (RMSDs) (in Å) of Average Structures from Molecular Dynamics Simulations with Respect to the NMR Reference Structure of the Drew–Dickerson Dodecamer (DDD)a.
| bsc0 | bsc1 | OL15 | CHARMM36 | CHARMM36-JCb | |
|---|---|---|---|---|---|
| TIP3P | 1.00 | 0.64 | 0.53 | 1.29 | 1.30 |
| OPC | 0.91 | 0.61 | 0.44 |
The average structure from simulations for each system was calculated over the full aggregated trajectory for that system; the DDD NMR reference was an average of the models in the 1NAJ structure. RMSDs were calculated over all heavy atoms of the internal eight base pairs.
CHARMM36-JC refers to the simulations with the Joung-Cheatham ion parameters.
