Figure 2
Equilibrium unfolding of LtPHBase in GdHCl. The black circles represent the average percentage of unfolded protein determined by three independent experiments. The line is a fit of the data to a two-state unfolding mechanism. The left inset shows the fluorescence emission intensity spectrum for the concentration points measured (0.0 M GdHCl for the top-most curve to 7.0 M GdHCl for the bottom-most curve). The insert on the right shows the shift of the maximum fluorescence emission wavelength as a function of denaturant concentration. |
