This book will bring you closer towards understanding how photosynthetic oxygen evolution works in high plants and micro algae, or cyanobacteria. To the time when this work was done, information on photosynthesis was largely based on experimental results obtained from studies on high plants, mainly spinach. Yet no crystal structure of photosystem 2 was available from high plants. In 2001, Dr. Zouni and co-workers from TU-Berlin had reported a crystal structure of photosystem 2 obtained at resolution 3.8 A from a thermophilic cyanobacteria Thermosynechococcus elongatus. Thus an important...
