Abstract
PF1163A (1) is a fungal metabolite that inhibits sterol-C4-methyl oxidase. In this study, we identified the biosynthetic gene cluster of 1 and elucidated its biosynthetic pathway through heterologous expression experiments. Polyketide synthase–nonribosomal synthetase hybrid PfaA, which is responsible for the biosynthesis of PF1163A, harbors an unusual domain organization with tandem condensation (C) domains and a terminal condensation domain. Mutagenesis studies suggest that both C domains are required for the function of PfaA.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
