Abstract

Oxygen evolution and proton release of crystallised photosystem II core complexes isolated from Synechococcus elongatus were measured. The yields show that the crystals themselves are capable of highly active water oxidation. This opens the possibility for the structural analysis of the outstanding water-oxidising apparatus.
