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 ...

Photosystem II (PSII) is a multiprotein complex that catalyzes the light-driven water-splitting reactions of oxygenic photosynthesis. Light absorption by PSII leads to the production of excited states ...

Future prospects for clean, green, renewable energy may hinge upon our ability to mimic and improve upon photosynthesis – the process by which green plants, algae and some bacteria convert solar ...

We are aiming to explore electron transfer and binding mechanisms between the soluble electron transfer proteins plastocyanin or cytochrome c6 and photosystem I (PSI) (Finazzi et al., 2005; Sommer et ...

In maize chloroplasts, the ratio of HCO3 - (anion) binding sites to high-affinity atrazine binding sites is unity. In the dark, atrazine noncompetitively inhibits the binding of half of the HCO3 - to ...

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.

In a new article published in Nature an international research team presents high-resolution images of photosystem II, the protein complex that splits water into hydrogen ions and oxygen during ...

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 ...
