title: Photosynthetic water oxidation: the role of tyrosine radicals.
abstract: This mini-review outlines the involvement of the tyrosine electron carriers, Y(D) and Y(Z), in the mechanism of electron transfer from water to P680. We discuss our data and put forward our ideas on the role of Y(D) and Y(Z).
