Polyketide Starter and Extender Units Serve as Regulatory Ligands to Coordinate the Biosynthesis of Antibiotics in Actinomycetes
Abstract
Numerous antibiotics are derived from polyketides, whose biosynthesis is accurately controlled by transcriptional regulators that respond to diverse physiological or environmental signals. It is generally accepted that antibiotics or biosynthetic intermediates serve as effectors to modulate their production in actinomycetes.
