Effects of Hydroxylamine on Photosystem II: II. Photoreversal of the NH(2)OH Destruction of O(2) Evolution.
The inactivation of O(2)-evolving centers by NH(2)OH extraction was shown to be reversible. This reversal required light and manganese. This light-induced restoration of active O(2)-evolving centers was analyzed using three green algae and the blue-green alga, Anacystis nidulans. The following results were obtained: [List: see text].
