The ''electrochemical activities'' of various substituted hydroxylamine and hydrazine compounds were compared with respect to their ability to interact with the intact O/sub 2/-evolving system. In addition it was shown that Mn/sup 2 +/ is a very effective donor to inactivated PSII centers (reaction rate of approximately 10/sup 2/ s/sup -1/ ..mu..M/sup -1/) but acts no differently than other artificial donors, and is not prebound at the inactivated centers.
