Common Namespheroidene
DescriptionSpheroidene is a carotenoid, a class of organic pigments synthesized by various microorganisms and plants. Its chemical structure features a long polyene chain, which is crucial for its photophysical properties. Spheroidene plays a significant role in photosynthetic organisms, particularly in the light-harvesting complexes of purple bacteria. For instance, it has been shown to achieve approximately 90% energy transfer efficiency (EET) when reconstituted into the LH2 complex of Rhodobacter sphaeroides (PMID:40736338 ). Additionally, spheroidene facilitates efficient energy transfer in the LH1 complex of Rhodospirillum rubrum (PMID:40736338 ). The carotenoid is also involved in unique relaxation dynamics within these complexes, contributing to the generation of specific states such as the carotenoid S* and T1 states (PMID:40005125 ). However, the production of certain metabolites like Q10 can deplete isoprene precursors, adversely affecting spheroidene levels (PMID:39626274 ). Recent studies have highlighted the genetic diversity and biosynthetic pathways associated with spheroidene and its related compounds, providing insights into the enzymes involved in carotenoid biosynthesis in purple sulfur and non-sulfur bacteria (PMID:37887056 ).
