Table 3.

Analysis of factors (listed in Table 1) that differentiate the populations of PA•+ and PB•+ in the PSI protein environment (in %)

Charge
Spin
PA•+ PB•+ PA PB
Wild-type 27.9 72.1 22.4 77.6
(1) + (2) 37.0 63.0 35.1 64.9
(1) + (3) 35.6 64.4 30.5 69.5
(1) + (2) + (3) 40.5 59.5 39.1 60.9

Factors (1) T743V (deletion of a H-bond with PA), (2) CH3COO− substitution with –H (deletion of the Chla′/Chla difference), and (3) deletion of charges of PsaA/PsaB residue pairs responsible for the Em(PA)/Em(PB) difference.
