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 <scene name='Photosystem_II/Protein_only/1'>alpha helices</scene> and is a symmetrical <scene name='Photosystem_II/Psii_dimer/1'>dimer</scene>. Fifteen subunits are in each monomer, with multiple subunits associated with the oxygen evolving complex missing | Photosystem II, crystallized from the bacteria, ''Thermosynechococcus elongatus'', at 3.50 Å, is representative of the photosynthetic protein found in cyanobacteria and plants.

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 <scene name='Photosystem_II/Hydrophobic_polar/1'>polar and hydrophobic</scene> residues helps to visualize its insertion into the membrane. | ||
