Role of the O4 Channel in Photosynthetic Water Oxidation as Revealed by Fourier Transform Infrared Difference and Time-Resolved Infrared Analysis of the D1-S169A Mutant.

Abstract excerpt

Photosynthetic water oxidation takes place at the Mn4CaO5 cluster in photosystem II. Although the atomic structures of its intermediates called S states have recently been reported, the catalytic mechanism of water oxidation has not been well understood. Here, to investigate the involvement of the O4 site of the Mn4CaO5 cluster and a water channel from O4 in the water oxidation reaction, we examined the effects...
