The Mechanism of Photosynthetic Water Oxidation

Atmospheric oxygen is produced from photosynthetic water splitting in a pigment-protein complex Photosystem II. The water splitting chemistry is remarkably efficient, yet the mechanism is unknown. Our studies will combine new biological material with innovative spectroscopic techniques. This unique approach will provide new and groundbreaking information about the location of substrate water binding and establish the precise chemical reaction pathway of the water splitting reaction. Our research will significantly advance Australian knowledge base in bio-inorganic catalysis while training a new generation of Australian scientist in biophysical chemistry.
