... to the layman the word ‘photosynthesis’ is usually associated with green plants, much of our understanding of the molecular basis of biological transduction of light energy has come from studies of purple photosynthetic bacteria. Their RCs (reaction centres) and attendant light-harvesting complexes have been...

...P.K. Fyfe; M.R. Jones Reaction centres are membrane-embedded pigment–protein complexes that transduce the energy of sunlight into a biologically useful form. The most heavily studied reaction centres are the PS-I (Photosystem I) and PS-II complexes from oxygenic phototrophs, and the reaction centre...

...M.C. Wakeham; M.R. Jones The purple bacterial reaction centre uses light energy to separate charge across the cytoplasmic membrane, reducing ubiquinone and oxidizing a c -type cytochrome. The protein possesses a macroscopic structural two-fold symmetry but displays a strong functional asymmetry...
