Incorporation of carotenoids into the reaction centers from the carotenoidless mutant of a purple photosynthetic bacterium Rhodobacter sphaeroides R26.1

摘要

Carotenoids play important roles in photosynthesis, such as light-harvesting and photoprotection. In the light-harvesting pigment-protein complexes (LH complexes) from purple photosynthetic bacteria, the efficiency of excitation energy-transfer from carotenoid to bacteriochlorophyll is found to vary from 30 to 90%.
