A Period-Four Infrared Signal from Active Water-Splitting Enzyme
The investigation of the molecular processes leading to the photolytic oxidation of water in plants and alga has been a continuous challenge for scientists. The protein units that perform the accumulation of the necessary redox equivalents in four consecutive light reactions have been studied in detail (for a recent review, see ). Much evidence for the mechanisms that control the withdrawing of electrons and the release of protons from water has been collected from spectroscopic experiments (for a review, see ). The techniques applied make use of the electronic transitions of prosthetic groups or pigments and thus can monitor only their direct environment. When applied in the UV, they may, in addition, be difficult to interpret.
