Model of the photosystem II core from Jonathan Nugent
The structure is a model (1) based on use of the bacterial reaction
center as a template. The authors have added residues in "missing" loops,
and refined the structure by a combination of computational approaches.
In the initial view, the protein is oriented with the acceptor side
(stroma facing domain) up, and the donor-side (lumen facing domain) down.
The D1 subunit is colored cyan, and the D2 subunit yellow. The chromophores
are shown as dark green spacefilling models.
