Abstract

This work has shown that binuclear and higher manganese clusters can bind water molecules reversibly and deprotonate them to form oxo bridges. Successively higher oxidation states may be stabilized by additional oxo-bridges. One can speculate that when the capacity for oxidation of the cluster is exceeded, oxygen is evolved and the whole process can begin again. This almost certainly is what is happening in the Mn-enzyme.
