However, most of these BGCs are silent under standard laboratory conditions. Streptomyces have a large number of secondary metabolite biosynthetic gene clusters (SM-BGCs) that may encode NPs. About two-thirds of natural antibiotics are produced by Streptomyces. Natural products (NPs) are critical sources of drug molecules for decades.
