Figure 9.
The proposed allosteric model reproduces the experimental data of W697X mutants. The figure depicts the normalized g-V curves obtained for the W697X mutants in the presence of presence at 1 µM (A) and 100 µM (B) of capsaicin. The solid lines depict the best fit to the allosteric model. Data were fitted to Eq. 3, fixing the following values for the equilibrium constants: Jo = 0.021, L = 5.0 × 10−4, Kd = 10−5, zg = 0.8, and E = 1. The values obtained for allosteric constants P and D and free energy are depicted in Table 4.
