Abstract: Streptomyces are famous for their ability to synthesize a large number of bioactive compounds as secondary metabolites containing antibiotics, enzyme inhibitors, and other small molecules with potential physiological activity (Niu et al., 2016; Song et al., 2019; Yin et al., 2019). Secondary metabolites are produced by a multi-step reaction of a primary metabolite as a precursor (Liu et al., 2013; Li et al., 2021). Therefore, it is of great research significance to increase the overall synthesis level of antibiotics by increasing the amount of synthesis of precursors.
