Inducing Global Expression of Actinobacterial Biosynthetic Gene Clusters

Bacteria produce an impressive array of bioactive specialized metabolites, with Streptomyces (and the actinobacteria more generally) being unusually diverse and prolific producers. However, the biosynthetic potential of these organisms has yet to be fully explored, as many of the biosynthetic gene clusters that direct the synthesis of these natural products are transcriptionally silent under laboratory growth conditions. Here, we describe …
