Figure 4.

Determination of the nonpolar solvation parameter at PagP site 111. The $\Delta \Delta G_{\text{w,l}}^{\text{o}}$ values of nonpolar residues were plotted as a function of their nonpolar accessible surface area in a G-X-Gly tripeptide, where X is any amino acid. The correlation is well described (R² = 0.91), with intercept equal to 0.156 and slope equal to 25 cal mol⁻¹ A⁻², which reflects the value of the σ_NP from bilayer to water.
