Abstract:
"Photosynthesis uses light energy to drive the oxidation of water at an
oxygen-evolving catalytic site within photosystem II ( PSII). We report the
structure of PSII of the cyanobacterium Thermosynechococcus elongatus
at 3.5 angstrom resolution. We have assigned most of the amino acid residues
of this 650-kilodalton dimeric multisubunit complex and refined the structure
to reveal its molecular architecture. Consequently, we are able to describe
details of the binding sites for cofactors and propose a structure of the
oxygen-evolving center (OEC). The data strongly suggest that the OEC contains
a cubane-like Mn3CaO4 cluster linked to a fourth Mn by a mono-mu-oxo bridge.
The details of the surrounding coordination sphere of the metal cluster and
the implications for a possible oxygen-evolving mechanism are discussed."
