TABLE 1.

Lifetimes resulting from target analysis of PS2 core complexes from WT Synechocystis sp. PCC 6803 and D2-His¹⁹⁷Gln and D2-His¹⁹⁷Ala mutants

	Lifetime 1	Lifetime 2	Lifetime 3	Lifetime 4	Lifetime 5
WT	2.7 ps	29 ps	39 ps	360 ps	35 ns
D2-His197Gln	4.0 ps	24 ps	31 ps	415 ps	36 ns
D2-His197Ala	2.3 ps	22 ps	27 ps	520 ps	40 ns

The analysis is based on the five-compartment kinetic scheme of Fig. 6.
