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 ...

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 ...

Researchers have, with the help of cryogenic electron microscopy, succeeded in producing a high-resolution image of photosystem II - the central complex of photosynthesis - of the model plant ...

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 ...

In the recent decade, scientists have paid more attention to studying light harvest for producing novel bionic materials or integrating naturally biological components into synthetic systems.

From providing living cells with energy, to nitrogen fixation, to the splitting of water molecules, the catalytic activities of metalloenzymes – proteins that contain a metal ion – are vital to life ...

More than two billion years ago, cyanobacteria began producing oxygen in Earth’s primarily toxic atmosphere. Since then, the photosystem II protein complex—now shared by land plants, algae, and ...

Photosystem II (PSII) is the only biological machine capable of splitting water into oxygen using sunlight. It plays a fundamental role in global oxygen production and solar energy conversion. However ...

RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in ...

Many proteins of the photosynthesis complexes are encoded by the genome of the chloroplast and synthesized by bacterium-like ribosomes within this organelle. To determine where proteins are ...
