A gene targeting system for A. terreus NIH2624 was developed and a gene cluster for terretonin biosynthesis was characterized. The intermediates and shunt products were isolated from the mutant strains and a pathway for terretonin biosynthesis is proposed. Analysis of two meroterpenoid pathways corresponding to terretonin in A. terreus and austinol in A. nidulans reveals that they are closely related evolutionarily.This document is the Accepted Manuscript version of a Published Work that appeared in final form in Organic Letters, copyright © American Chemical Society after peer review and technical editing by the publisher.
