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 ...

Using ultrafast, intensely bright pulses of X-rays scientists have obtained the first ever images at room temperature of photosystem II, a protein complex critical for photosynthesis and future ...

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 ...

Scientists have decoded the atomic structure of Photosystem I from a 3-billion-year-old cyanobacteria lineage, offering a unique look at early oxygen-producing photosynthesis. The ancient ...

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 ...
