Low-temperature photochemistry in photosystem II from Thermosynechococcus elongatus induced by visible and near-infrared light.

Abstract

The active site for water oxidation in photosystem II (PSII) consists of a Mn4Ca cluster close to a redox-active tyrosine residue (TyrZ). The enzyme cycles through five sequential oxidation states (S0 to S4) in the water oxidation process. Earlier electron paramagnetic resonance (EPR) work showed that metalloradical states, probably arising from the Mn4… (More)
