Summary
Photosystem II has unusual properties compared to Photosystem I and the other electron transport complexes in the thylakoid membrane. Its relatively compact protein structure accommodates a large number of pigment and cofactor ligands. The D1 protein of the reaction center heterodimer turns over more rapidly than any of the other proteins in the photosystem or indeed in the chloroplast. Irradiance in excess of requirements for saturating photosynthesis cause photoinhibition, considered by some to be due to photodamage of PS II, by others to constitute a change in functionality of this photosystem. The latter suggestion and possible mechanisms are discussed in this chapter.
