Table 1. Color-Coded Criterion Based on the Predicted Free Energy Difference (ΔΔG) Range of Values Adopted to Compare in Silico Results and Experimental Evidencea.
| mutation effect | ΔΔG range (kcal/mol) | color code |
|---|---|---|
| Neutral mutations | –0.25 ≤ ΔΔG ≤ +0.25 | Gray |
| Mildly destabilizing mutations | –2.00 ≤ ΔΔG < −0.25 | Light Yellow |
| Destabilizing mutations | –4.00 ≤ ΔΔG < −2.00 | Light Red |
| Highly destabilizing mutations | –4.00 < ΔΔG | Red |
| Stabilizing mutations | +0.25 < ΔΔG ≤ +1.00 | Light Green |
| Highly stabilizing mutations | ΔΔG > +1.00 | Green |
a
Negative/positive ΔΔG values indicate unfavorable/favorable substitutions for the mutant residue in the relevant position, respectively.
