Photosystem II (PSII) is the only biological machine capable of splitting water into oxygen using sunlight. It plays a ...

A set of breakthroughs from scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) is ...

Cyanobacteria began contributing oxygen to Earth's mostly noxious atmosphere more than 2 billion years ago. The photosystem II protein complex now shared by various lineages of cyanobacteria, algae ...

Photosystem II microcrystals (approximately 10 micrometers in diameter)were used as a matter of efficiency. Molecular reconstruction through X-ray diffraction requires the examination of ...

A recent study from Japan uncovered the dynamics of Photosystem II during water oxidation, using cutting-edge pump-probe serial femtosecond X-ray crystallography. The study revealed rapid ...

Heat and water deficit stresses tend to impede and restrict the efficiency of photosynthesis, chlorophyll fluorescence and maximum photochemical quantum yield in plants based on their characteristic ...

Photosynthesis plays a crucial role in shaping and sustaining life on Earth, yet many aspects of the process remain a mystery. One such mystery is how Photosystem II, a protein complex in plants ...

PHOTOSYSTEM II SUBUNIT R is required for efficient binding of LIGHT-HARVESTING COMPLEX STRESS-RELATED PROTEIN3 to photosystem II-light-harvesting supercomplexes in Chlamydomonas reinhardtii. Plant ...

A GIF of the structural changes of Photosystem II and its catalytic center (Mn4Ca cluster) during the water oxidation reaction. The movie shows the S2 to S3 transition step, where the first water ...
