Figure 2.

Transition diagram constructed from the CD spectra in Fig. 1, A and B. The plot shows the ellipticity at 200 vs. 222 nm. Some points are labeled with their [TFE], and the labels are color-coded to show pH. (Solid lines) Fits to the pH 2.4 points derived from spectra that share isodichroics (Fig. 1A, insets).
