Polycyclic tetramate macrolactams (PTMs) are a family of structurally and biomedically interesting natural products. Despite these properties and the resulting potential applications, only little is known about PTM biosynthesis. We now successfully identified and functionally studies the ikarugamycin biosynthetic gene cluster from Streptomyces sp. Tü6239. By using a newly developed heterologous production system we showed that only three genes are necessary for the biosynthesis of this natural product. In addition, the application of so-called PTM hydroxylases led to the first proof and utilization of the promiscuity of PTM biosynthetic enzymes to generate new molecules.
