Substituting Fe for two of the four Mn ions in photosystem II—effects on water-oxidation

We have investigated the interaction of Fe(II) cations with Ca-depleted PSII membranes (PSII[-Ca,4Mn]) in the dark and found that Fe(II) incubation removes 2 of 4 Mn ions from the tetranuclear Mn cluster of the photosynthetic O 2 -evolving complex (OEC). The reduction of Mn ions in PSII(-Ca,4Mn) by...
