TABLE I.

Thermodynamic parameters ΔH, ΔS, and ΔG (at 300 K) of the dynamic transition in heme proteins. The free energy is negative at 300 K, which means that the molecular population shift from the rigid states (CS) to the flexible state.

	Nitrophorin ^a (Fe³⁺)	Myoglobin ^b deoxy (Fe²⁺)	Myoglobin ^a met (Fe³⁺)
ΔH [kJ mol⁻¹]	18.3 ± 3.7	25.9	21.0 ± 1.0
ΔS [kJ mol⁻¹ K⁻¹]	0.063 ± 0.020	0.107	0.080 ± 0.004
ΔG_trans at 300 K	−0.6 kJ/mol	−4.1 kJ/mol	−3 kJ/mol
