Metabolite Identification
Common NameAsperterpenoid B
DescriptionAsperterpenoid B is a sesterterpene, a class of chemical compounds characterized by a 25-carbon skeleton. This metabolite is synthesized through a biosynthetic pathway involving multiple enzymes in the fungus Aspergillus oryzae. The process begins with the gene cluster that includes astC, which encodes a sesterterpene cyclase responsible for the formation of preasperterpenoid A. This intermediate is then oxidized by the P450 enzyme AstB, leading to the production of asperterpenoid A and a minor product, asperterpenoid B. Additionally, asperterpenoid A undergoes further oxidation by another P450 enzyme, AstA, resulting in the formation of asperterpenoid C. The intricate enzymatic transformations highlight the complex biosynthetic pathways involved in the generation of these sesterterpenes, showcasing the enzymatic roles in the oxidation and cyclization processes critical for their structural diversity (PM...).
