Fig. 4.
Far-UV CD spectra of SNase variants with internal Glu (A) and internal Lys (B). Also shown are the background protein in water (●), wild-type SNase unfolded in 6 M GdmCl (▲), and an unfolded T62P variant in water (△). The lines are meant only to guide the eye. All measurements at pH 7 in 25 mM Hepes and 100 mM KCl.
