Photosynthetic light-harvesting complexes play important roles in the early events in photosynthesis in nature, and have been studied by various spectroscopic methodologies. Single molecule spectroscopy is one of the recent powerful methods to study fine electronic structures of photosynthetic light-harvesting complexes without averaging over an ensemble of the complexes. In this review, we focus...
In the final stage of bacteriochlorophyll (BChl) biosynthesis, the presence of BChl-a molecules possessing dihydrogeranylgeranyl and tetrahydrogeranylgeranyl groups at the 17-propionate has been reported. However, the molecular structures of such BChls-a have not yet been determined in terms of the positions of CC double bonds in the 17 2 -ester. In this study, we isolated significant amounts...
Supramolecular structures in extramembraneous antennae of green photosynthetic bacteria (so-called chlorosomes ) are reviewed. In chlorosomes, bacteriochlorophylls-c, d and e (magnesium complexes of chlorins with a 1-hydroxyethyl group) self-aggregate to form the main light-harvesting components. This arrangement is unique and different from that in other antennae where the pigments bond with...
