The ubiquitous catechol moiety elicits siderophore and angucycline production in Streptomyces

Abstract

The biosynthetic gene clusters of Actinobacteria are poorly expressed in the laboratory, necessitating a better understanding of the signals that promote their expression in order to exploit their full biosynthetic potential. Here, the authors show that the stress hormone epinephrine elicits the expression of biosynthetic gene clusters and influences the metabolism of Streptomyces, with the catechol moiety proving key to this response.
