Kinetics and thermodynamics of heme-c to heme-d₁ intramolecular ET process in H369A P. aeruginosa-NiR at 298 K

Kinetic parameters	k/s−1	ΔH‡/kJ mol−1	ΔS‡/J K−1 mol−1
forward, k23	12.8 ± 1.6	53 ± 10	−48 ± 8
reverse, k32	11.7 ± 1.5	58 ± 10	−32 ± 5
Equilibrium parameters	K23	ΔH0/kJ mol−1	ΔS0/J K−1 mol−1
	∼1.1	Not determined	Not determined

Data are presented for the initial, first electron equilibration.

Because of the limited amount of the H369A mutant, the results are based on measurements at three different temperatures, only.
