Change of p53-DNA interaction energies (kcal/mol) with R273H mutations in Puma BS2 complex
| Mutated Monomersa | H14 mode | T13 mode |
|---|---|---|
| Double mutants | ||
| a1b1 | 48 | 52 |
| a1a2 | −132 | −119 |
| a1b2 | 12 | 23 |
| b1a2 | 44 | 54 |
| b1b2 | 177 | 187 |
| a20b2 | 9 | 49 |
| Triple mutants | ||
| b1a2b2 | 204 | 226 |
| a1a2b2 | 46 | 75 |

| a1b1a2 | 72 | 91 |
aFour p53 monomers are labeled with b1 and b2 binding DNA sequence specifically and a1 and a2 binding DNA non-specifically. Positive interaction energy means repulsion and negative number means attraction. For T24 and Q1234 modes, the interaction energies are always repulsive.
