Metabolite Identification
Common NameAsperterpenoid C
DescriptionAsperterpenoid C is a sesterterpene, a class of terpenoids characterized by a 25-carbon skeleton. This compound is synthesized through a series of enzymatic reactions involving a gene cluster in the fungus Aspergillus oryzae. The biosynthetic pathway begins with the gene astC, which encodes a sesterterpene cyclase that converts precursors into preasperterpenoid A. This intermediate is then oxidized by the P450 enzyme AstB to produce asperterpenoid A and a minor product, asperterpenoid B. Subsequently, asperterpenoid A undergoes further oxidation by another P450 enzyme, AstA, leading to the formation of asperterpenoid C. The intricate enzymatic steps highlight the complexity of sesterterpene biosynthesis in fungi, illustrating the roles of cyclases and cytochrome P450 enzymes in generating diverse terpenoid structures (PM...).
