Photosystems I and II: Structure, Proteins, and Cofactors

Over the last few years it has become increasingly clear that considerable homology exists between the acceptor side components of photosystem II (PS II) and those of reaction centers from purple photosynthetic bacteria (Parson and Ke 1982, Crofts and Wraight 1983, Dutton, Chap. 5, Michel and Deisenhofer, Chap. 8.4, both this Vol.). While one might hardly have expected to see familiar faces among the high potential donors of PS II, recent evidence suggests that some of the same old dogs may have learned new tricks.
