image: Caltech scientists synthesized a structural model of the oxygen-evolving complex from photosystem 11. This synthetic model provides insight into the role of calcium in biological dioxygen generation. This image relates to an article that appeared in the Aug. 5, 2011, issue of Science, published by AAAS. The study, by Dr. J.S. Kanady of the California Institute of Technology in Pasadena, Calif., and colleagues was titled, "A Synthetic Model of the Mn3Ca Subsite of the Oxygen-Evolving Complex in Photosystem II." view more
