Harnessing the power of photosynthesis to catalyze novel light-driven redox chemistry
requires a way to intercept electron flow directly from the photosynthetic electron transport …

Photosystem I (PSI) is a large pigment-protein complex that unites a reaction center (RC) at
the core with∼ 100 core antenna chlorophylls surrounding it. The RC is composed of two …

The proliferation of phototrophy within early-branching prokaryotes represented a significant
step forward in metabolic evolution. All available evidence supports the hypothesis that the …

Photosystem I has two branches of cofactors down which light-driven electron transfer (ET)
could potentially proceed, each consisting of a pair of chlorophylls (Chls) and a …

Photosystem I has two active electron-transfer pathways. However, electron transfer occurs
primarily along one of the two branches (A-branch) irrespective of the similar protein …

The Q y absorption spectrum of Photosystem-I from Thermosynecochoccus elongatus
(formerly Synecochoccus elongatus) is calculated using the CAM-B3LYP density functional …

The redox potential of the primary electron donor P700, E m (P700/P700+), of Photosystem I
(PSI) has been determined for 10 oxygenic photosynthesis organisms, ranging from …

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 …

We studied the kinetics of reoxidation of the phylloquinones in Chlamydomonas reinhardtii
Photosystem I using site-directed mutations in the PhQA-binding site and of the residues …

Photosynthetic reaction centers are the membrane–protein complexes responsible for the
capture and storage of light energy in photosynthetic organisms. These proteins contain a …
