Figure 2. The effect on the thermal stability of the cluster and period replacement mutants.

Figure 2

Fraction folded as measured by relative ellipticity at 222 nm as a function of temperature in 500 mM NaCl, 10 mM sodium phosphate pH 7.5, 1 mM EDTA, 0.5 mM DTT. The tropomyosin concentration was 0.01 mg/ml (1.6 µM). The TMs are reported in Tables 2 and 3. The fraction folded is relative to the mean residue ellipticity at 0°C where the proteins were fully folded. A. Symbols: •, wildtype; ○, P3Shift, ▾, P2Shift. B. Symbols: •, wildtype; ○, P2P3Shift. C.
