Sentences with phrase «in photosystem»

Using the world's most powerful x-ray laser, an international collaboration led by Berkeley Lab researchers took femtosecond «snapshots» of water oxidation in photosystem II, the only known biological system able to harness sunlight for splitting the water molecule.

X-ray free electron laser and mass spectrometric studies into the mechanism of water oxidation in photosystem II

Working at SLAC's Linac Coherent Light Source (LCLS), the world's most powerful x-ray laser, the researchers were able to take detailed «snapshots» of the four photon - step cycle for water oxidation in photosystem II, a large protein complex in green plants.

This represents a major advance towards the real time characterization of the formation of the oxygen molecule in photosystem II, and has yielded information that should prove useful for designing artificial solar - energy based devices to split water.»
