Investigating the initial steps of auricin biosynthesis using synthetic biology.

ABSTRACT: Streptomyces lavendulae subsp. lavendulae CCM 3239 (formerly Streptomyces aureofaciens CCM 3239) contains a type II polyketide synthase (PKS) biosynthetic gene cluster (BGC) aur1 whose genes were highly similar to angucycline BGCs. However, its product auricin is structurally different from all known angucyclines. It contains a spiroketal pyranonaphthoquinone aglycone similar to griseusins and is modified with D-forosamine. Here, we describe the characterization of the initial steps in auricin biosynthesis using a synthetic-biology-based approach. We have created a plasmid system based on the strong kasOp* promoter, RBS and phage PhiBT1-based integration vector, where each gene in the artificial operon can be easily replaced by another gene using unique restriction sites surrounding each g
