Kinetic parameters of O₂ release (slow phase) for WT and mutant thylakoid membranes

	Ea (kJ·mol−1)	A (s−1)	tslow* (ms)	ΔSǂ (J·mol−1 K−1)	ΔHǂ (kJ·mol−1)
WT	45.8	5.2 × 1010	1.1	−47.1	43.7
V185N	22.3	1.9 × 105	29.3	−150.9	20.1
D61N	44.2	1.5 × 109	22.9	−77.4	41.8
D61A	35.3	3.3 × 107	32.8	−109.2	32.9

The uncertainties in the activation energies are of the order of ±2.

^*The values for the individual time constants are measured at 27 °C.
