The primary light-harvesting processes, energy transfer in the light-harvesting antenna, and trapping of the excited states by reaction centers were studied in several mutant strains of the photosynthetic purple bacterium Rhodobacter sphaeroides. The mutants had reaction centers in which the rates of electron transfer were modified by site-directed mutations at the M210 position. Low-intensity pump-probe laser spectroscopy was used to monitor the absorbance transients in the Qy region of the… CONTINUE READING
