Photoprotection in a purple phototrophic bacterium mediated by oxygen-dependent alteration of carotenoid excited-state properties

is present the incorporation of the keto group into spheroidene, forming spheroidenone. The spheroidene/spheroidenone transition acts as a molecular switch, which is suggested of singlet oxygen. We propose that spheroidene...

Excitation Energy Transfer Dynamics from Carotenoid to Bacteriochlorophyll a in the LH2 Complex of Rhodobacter sphaeroides: Insights from Reconstitution Experiments with Carotenoids and B800 Bacteriochlorophyll a

Carotenoids are crucial for photosynthesis, playing key roles in light harvesting and photoprotection. In this study, spheroidene and bacteriochlorophyll a (Bchl a) were reconstituted into the chromatophores of the carotenoidless mutant in r...

Spectroscopic properties of the S-1 state of linear carotenoids after excess energy excitation

Properties of the S-1 state of neurosporene, spheroidene and lycopene were studied after excess energy excitation in the S-2 state. Excitation of carotenoids into higher vibronic levels of the S-2 state generates excess vibrational energy in...

Photophysical consequences of spheroidene reconstitution in LH1 of Rsp. rubrum: improved energy transfer and altered photoprotection

-inspired LH systems and artificial photosynthesis. Here, we reconstituted spheroidene altered photoprotective dynamics. These findings suggest that while spheroidene......
