Abstract excerpt

Photosystem II (PSII) catalyzes water oxidation into electrons, protons and dioxygen at its catalytic center, a Mn4CaO5 cluster, utilizing light energy. An amino acid residue D1-V185 in the D1 protein is located close to the Mn4CaO5 cluster, and plays a critical role in its catalytic function. In this research we purified PSII dimers from a D1-V185T mutant of Thermosynechococcus vestitus and analyzed its...
