Figure 4
Equilibrium unfolding of T. aquaticus SCS. The changes in ellipticity were measured as a function of the concentration of denaturant using either 2.2 µM (circles) or 9.0 µM (filled circles) enzyme in 5 mM 2-mercaptoethanol, 0.1 mM EDTA, 60 mM potassium phosphate pH 7.4. The two transitions are labelled 1 and 2. |
