Metabolite Identification
Common NameAspercryptin
DescriptionAspercryptin is a lipopeptide metabolite characterized by its unique structural orientation, which diverges from conventional lipopeptides. Its chemical structure includes two noncanonical amino acids derived from octanoic and dodecanoic acids, synthesized through a 14-gene biosynthetic gene cluster in Aspergillus nidulans. This cluster encodes two fatty acid synthases and several enzymes that facilitate the conversion of saturated fatty acids into α-amino acids, highlighting the complexity of its biosynthetic pathway (PMID:27310134 ). The transcription factor AtnN plays a critical role in regulating the expression of the aspercryptin gene cluster, particularly under stress conditions induced by menadione sodium bisulfite (MSB) treatment (PMID:39643398 ). Recent studies have revealed the existence of multiple aspercryptin variants, with increases in their levels observed following the inhibition of histone deacetylase, suggesting an intricate interplay between genetic regulation and secondary metabolite production (PMID:27310134 ). Additionally, the discovery of aspercryptin was facilitated by the development of genetic dereplication strains, which allowed researchers to propose its biosynthetic pathway and confirm its formation from compounds produced by distinct gene clusters (PMID:26563584 ).
