Abstract
At the request of the organizer of this special edition, we have attempted to do several things in this manuscript: (1) we present a mini-review of recent, selected, works on the light-induced inorganic biogenesis (photoactivation), composition and structure of the inorganic core responsible for photosynthetic water oxidation; (2) we summarize a new proposal for the evolutionary origin of the water oxidation catalyst which postulates a key role for bicarbonate in formation of the inorganic core; (3) we summarize published studies and present new results on what has been learned from studies of 'inorganic mutants' in which the endogenous cofactors (Mn(n+), Ca 2+, Cl-) are substituted; (4) the first ΔpH changes measured during the photoactivation process are reported and used to develop a model for the stepwise photo-assembly process; (5) a comparative analysis is given of data in the literature on the kinetics of substrate water exchange and peroxide binding/dismutation which support a mechanistic model for water oxidation in general; (6) we discuss alternative interpretations of data in the literature with a view to forecast new avenues where progress is needed.
