BackgroundBackground
Photosystem II, crystallized from the bacteria, Thermosynechococcus elongatus, at 3.50 Å, is representative of the photosynthetic protein found in cyanobacteria and plants. The protein is associated with a variety of ligands. It is mainly composed of and is a symmetrical . Fifteen subunits are in each monomer, with multiple subunits associated with the oxygen evolving complex missing from this crystallization. Photosystem II is a membrane bound protein found in the thylakoid membrane of chloroplasts. Analysis of residues orients the protein within the membrane.
