Metabolite Identification
Common Nameneopentalenolactone D
DescriptionNeopentalenolactone D is a member of the chemical class of lactones, specifically a metabolite involved in the biosynthetic pathways of pentalenolactones. Its structure is characterized by a unique arrangement of carbon atoms resulting from the oxidation of 4, as catalyzed by avermitilis, which leads to a migration of more substituted methane groups (PMID:27933799 ). This compound has been shown to be produced through the Baeyer-Villiger oxidation of 1-deoxy-11-oxopentalenic acid when incubated with the recombinant PtlE protein from Streptomyces avermitilis in the presence of NADPH and catalytic FAD, indicating its role in a new branch of the pentalenolactone biosynthetic pathway (PMID:19485417 ). Furthermore, structural analysis of neopentalenolactone D methyl ester has been conducted using GC-MS, NMR, and X-ray crystallography, confirming its stereochemistry (PMID:19485417 ). Additionally, incubation of neopentalenolactone D with various enzymes has yielded other compounds, such as PL308 and neopentalenolactone E, highlighting its involvement in complex metabolic processes (PMID:21250661 ).
