Our current understanding of the PSII reaction centre owes a great deal to comparisons to
the simpler and better understood, purple bacterial reaction centre. Here we provide an …

Photosystem II (PSII) uses solar energy to oxidize water and delivers electrons for life on
Earth. The photochemical reaction center of PSII is known to possess two stationary states …

Electron transfer is used as a probe for angstrom-scale structural changes in single protein
molecules. In a flavin reductase, the fluorescence of flavin is quenched by a nearby tyrosine …

High resolution x-ray diffraction data from crystals of the Rhodobacter sphaeroides
photosynthetic reaction center (RC) have been collected at cryogenic temperature in the …

The primary reaction of photosynthesis is light-driven charge separation, carried out in
reaction centres, which are complexes of integral membrane proteins and cofactors. The …

Photosystem II (PSII) uses solar energy to oxidize water and delivers electrons to fix CO2.
