The protein composition of photosystem I (PSI) was examined in Nicotiana spp. by high-resolution polyacrylamide gel electrophoresis, N-terminal amino acid sequencing, and immunoblot analysis. Five PSI ...

This is a preview. Log in through your library . Abstract With the aim to specifically study the molecular mechanisms behind photoinhibition of photosystem I, stacked spinach (Spinacia oleracea) ...

One longstanding puzzle concerning photosystem II, a core component of photosynthesis, is that only one of the two symmetric branches in its reaction centre is active in electron transfer. To ...

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 ...

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 ...

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 research team has produced a semi-artificial electrode that could convert light energy into other forms of energy in biosolar cells. The technique is based on the photosynthesis protein Photosystem ...

Cryo-electron microscopy confirms that controlled alignment of Photosystem I on graphene boosts electron flow and durability ...

Definition: A photosystem that contains an iron-sulfur reaction center associated with accessory pigments and electron carriers. In cyanobacteria and chloroplasts, photosystem I functions as a ...

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.

Researchers at the SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory (along with collaborators in Sweden, Germany and the UK) have shed new light on the final step of ...
