Abstract excerpt
PSII generates strong oxidants used for water oxidation. The secondary electron donor, Y(Z), is Tyr161 on PSII reaction center D1 protein and mediates electron transfer from the oxygen-evolving Mn(4)CaO(5) cluster to the primary electron donor, P680. The latest PSII crystal structure revealed the presence of a hydrogen bond network around Y(Z), which is anticipated to play important roles in the electron and...
