Electron transfer in photosystem I.
This mini-review focuses on recent experimental results and questions, which came up since the last more comprehensive reviews on the subject. We include a brief discussion of the different techniques used for time-resolved studies of electron transfer in photosystem I (PS I) and relate the kinetic results to new structural data of the PS I reaction centre.
متن کاملPortable visible and near-infrared spectrophotometer for triglyceride measurements.
An affordable and portable machine is required for the practical use of visible and near-infrared (Vis-NIR) spectroscopy. A portable fruit tester comprising a Vis-NIR spectrophotometer was modified for use in the transmittance mode and employed to quantify triglyceride levels in serum in combination with a chemometric analysis. Transmittance spectra collected in the 600- to 1100-nm region were ...

متن کاملElectron transfer reactions of redox cofactors in spinach photosystem I reaction center protein in lipid films on electrodes.
Thin film voltammetry was used to obtain direct, reversible, electron transfer between electrodes and spinach Photosystem I reaction center (PS I) in lipid films for the first time. This reaction center (RC) protein retains its native conformation in the films, and AFM showed that film structure rearranges during the first several minutes of rehydration of the film. Two well-defined chemically ...
متن کاملThe assembly of protein subunits and cofactors in photosystem I.
The recently determined crystal structures of photosystems I and II at 2.5 A and 3.8 A resolution, respectively, have improved the structural basis for understanding the processes of light trapping, exciton transfer and electron transfer occurring in the primary steps of oxygenic photosynthesis. Understanding the assembly of the 12 protein subunits and 128 cofactors in photosystem I allows us t...
