Abstract:
We report the draft genome sequence of marine-derived Streptomyces sp. TP-A0882, a producer of buryrolactol, an antifungal γ-lactone-containing polyketide. The genome harbored at least three type I polyketide synthase (PKS), three type II PKS, four nonribosomal peptide synthetase (NRPS) and two hybrid PKS/NRPS gene clusters. Annotation of gene functions enabled us to identify the type I PKS gene cluster for butyrolactol biosynthesis and propose a plausible biosynthetic pathway for this unique polyketide.
