| Abstract: | Years of genetic, biochemical, and structural work have provided a number of insights into the oxygen evolving complex (OEC)
of Photosystem II (PSII) for a variety of photosynthetic organisms. However, questions still remain about the functions and
interactions among the various subunits that make up the OEC. After a brief introduction to the individual subunits Psb27,
PsbP, PsbQ, PsbR, PsbU, and PsbV, a current picture of the OEC as a whole in cyanobacteria, red algae, green algae, and higher
plants will be presented. Additionally, the role that these proteins play in the dynamic life cycle of PSII will be discussed. |
