Metabolite Identification
Common NamePentalenolactone D
DescriptionPentalenolactone D is a member of the chemical class of lactones, specifically a cyclic ester derived from pentalenic acid. Its biosynthesis involves the flavin-dependent Baeyer-Villiger oxidation of 1-deoxy-11-oxopentalenic acid, catalyzed by enzymes from various Streptomyces species, including Streptomyces arenae and Streptomyces avermitilis (PMID:27933799 ). This reaction results in the migration of a methylene carbon to form pentalenolactone D. Additionally, pentalenolactone D serves as a substrate for further enzymatic transformations, being oxidized to pentalenolactone E and F by recombinant enzymes such as PenD, PntD, and PtlD (PMID:21250661 ). The compound is also involved in the production pathways of neopentalenolactone D, which represents a new branch of the pentalenolactone biosynthetic pathway (PMID:19485417 ). The structural characterization of neopentalenolactone D has been achieved through techniques like GC-MS, NMR, and X-ray crystallography (PMID:19485417 ). Thus, pentalenolactone D plays a crucial role in the complex biosynthetic network of pentalenolactones, contributing to the diversity of metabolites produced by these actinobacteria.
