Abstract

Using models derived from the X-ray structure of photosystem II, it is shown that the oxygen evolving complex in the S ₂ state exists in two energetically similar and interconvertible forms. A longstanding question regarding the spectroscopy of the catalyst is thus answered: one form corresponds to the multiline g=2.0 EPR signal (see picture, right; O red, Mn purple, Ca yellow), and the other to the g<4.1 signals (left).
