Stability parameters for the apoMb variants1
| ApoMb Variant | KNI0 | KIU0 | 1/KNU0 |
|---|---|---|---|
| WT | 0.021 | 0.019 | 2500 |
| H64F | 0.0061 | 0.011 | 15000 |
| T67P | 0.67 | 0.029 | 51 |
| V68T | 0.13 | 0.017 | 450 |
| H97D | 0.013 | 0.061 | 1300 |
The GuHCl-induced unfolding measurements were carried out in 10 mM potassium phosphate pH 7, 20 °C. The KNI0 and KIU0 were obtained by fitting simultaneously both CD and Fluorescence signals for the unfolding of the apoMb variants to the 3-state unfolding mechanism using Equation 3 (see Supplementary Material, Table S1). The values of mNI and mIU were set to 2.35 and 1.36 kcal mol−1 M−1, respectively.
