Biosynthesis of AS2077715 and Funiculosin: Pathway Reconstitution and Identification of Enzymes that Form the All- cis Cyclopentanetetraol Moiety

J Am Chem Soc. 2023 Mar 29;145(12):6643-6647. doi: 10.1021/jacs.3c01681. Epub 2023 Mar 15.

Abstract

The complete biosynthetic pathways of the potent antifungals AS2077715 (1) and funiculosin (2) are reconstituted and characterized. A five-enzyme cascade, including a multifunctional flavin-dependent monooxygenease and a repurposed O-methyltransferase, is involved to perform the dearomatization, stereoselective ring contraction, and redox transformations to morph a hydroxyphenyl-containing precursor into the unusual all-cis cyclopentanetetraol moiety.
