One of its molecular mysteries of photosynthesis involves how the photosystem II protein complex harvests energy from sunlight and uses it to split water into hydrogen and oxygen. Now, an international team of researchers has used femtosecond pulses from an X-ray free electron laser (XFEL) at the Department of Energy’s SLAC National Accelerator Laboratory to capture the highest resolution room-temperature (RT) images of this protein complex, allowing scientists to watch closely how water is split during photosynthesis at the temperature at which it occurs naturally. A paper on the work is published in the journal Nature . The international research team is a long-standing collaboration between SLAC and Berkeley Lab, and includes Humboldt University in Germany, Umeå University and Uppsala […]
