PCR-Independent Method of Transformation-Associated Recombination Reveals the Cosmomycin Biosynthetic Gene Cluster in an Ocean Streptomycete.


ABSTRACT: The transformation-associated recombination cloning methodology facilitates the genomic capture and heterologous expression of natural product biosynthetic gene clusters (BGCs). We have streamlined this procedure by introduction of synthetic DNA gene blocks for the efficient capture of BGCs. We show the successful capture and expression of the aromatic polyketide antitumor agent cosmomycin from streptomycete bacteria and the discovery of new cosmomycin analogues by mass spectral molecular networking.
