Table 1.

Thermodynamic parameters of nsP4-CHIKV unfolding by CD spectroscopy.

Rate (°C/min) Tm (°C) ΔHapp (kcal/mol) ΔSapp (cal/mol K)
0.5 41.8 ± 0.2 122 ± 12 387 ± 38
1.0 43.7 ± 0.2 104 ± 8 331 ± 26

The Tm and the ΔHapp were determined by fitting the CD data to a two-state equilibrium model28. The ΔSapp of the unfolding transition at Tm was calculated as ΔSapp = ΔHapp/Tm since ΔG = 0 at Tm.
