Common Namedemethylspheroidene
Descriptiondemethylspheroidene is a yellow carotenoid belonging to the chemical class of terpenoids. Its chemical structure features a series of conjugated double bonds, which contribute to its characteristic pigmentation and potential photoprotective properties. Demethylspheroidene is synthesized through the spheroidene pathway, where it is produced alongside other carotenoids such as spheroidenone and neurosporene. In the biosynthetic process, demethylspheroidene is converted to spheroidene by the action of O-methyltransferase (PMID:16158287 ). This compound is notably accumulated in certain anaerobic-phototrophic bacteria, such as Rhodovulum sulfidophilum and Rhodobaca bogoriensis, particularly in conditions that promote light exposure (PMID:16086104 , PMID:16228308 ). The presence of demethylspheroidene has been linked to the adaptation of these organisms to their phototrophic lifestyle, suggesting a role in photosynthesis (PMID:16086104 ). Additionally, its synthesis can be influenced by genetic modifications, as demonstrated in studies involving crtA-deleted mutants (PMID:16086104 ). Overall, demethylspheroidene is an important intermediate in carotenoid biosynthesis, contributing to the diversity of carotenoids found in various microbial species.
