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 کاملLight-induced dynamics in photosystem I electron transfer.
Protein dynamics are likely to play important, regulatory roles in many aspects of photosynthetic electron transfer, but a detailed description of these coupled protein conformational changes has been unavailable. In oxygenic photosynthesis, photosystem I catalyzes the light-driven oxidation of plastocyanin or cytochrome c and the reduction of ferredoxin. A chlorophyll (chl) a/a' heterodimer, P...
متن کاملRelease of oxidized plastocyanin from photosystem I limits electron transfer between photosystem I and cytochrome b6f complex in vivo.
We used fast absorbance spectroscopy to investigate in vivo binding dynamics and electron transfer between plastocyanin (pc) and photosystem I (PSI), and cytochrome (cyt) f oxidation kinetics in Chlamydomonas reinhardtii mutants in which either the binding or the release of pc from PSI was diminished. Under single flash-excitation conditions, electron flow between PSI and the cyt complex was no...
متن کاملEnergy transfer and trapping in photosystem I.
The primary processes in all photosynthetic systems involve the absorption of energy from (sun) light by chromophores in a light harvesting antenna, and the subsequent transfer of this energy to a reaction centre (RC) site where the energy is `trapped' by means of a stable charge separation. Photosystem (PS) I is one of two such photosystems in oxygenic photosynthesis. When co-operating with PS...
