(a) C_p transition curve of β-HaH in buffer 20 mM HEPES (pH 7.06 at 80°C), recorded at scan rate of 1°C min⁻¹ and different protein concentrations: 1.01 mg·ml⁻¹ (blue line), 1.91 mg·ml⁻¹ (red line), and 2.88 mg·ml⁻¹ (black line). (b) C_p transition curve of α_D+N-HaH in buffer 20 mM HEPES (pH 7.06 at 80°C), recorded at scan rate of 1°C min⁻¹ and different protein concentrations: 2.0 mg·ml⁻¹ (blue line), 3.0 mg·ml⁻¹ (black line), and 4.52 mg·ml⁻¹ (red line).
