Table 1. Correlation Coefficient and PI Values for the Experimental Binding Affinities and the Calculated Binding Energies Before and After ONIOM Geometry Optimizationsa.
MM | MFMO | |
---|---|---|
before ONIOM | 0.553 (0.553) | 0.557 (0.508) |
after ONIOM | 0.467 (0.512) | 0.713 (0.783) |
The values in parentheses denote the PI values, whereas the others denote the correlation coefficient R values. For structures of the tankyrase 2–ligand complexes before and after ONIOM geometry optimizations, these values on the MM- or MFMO-based binding energies are shown.
