WebAs the erythromycin biosynthesis was recently shown to positively correlate with the ATP/ADP ratio in Sac. erythraea (Li et al., 2024), we inferred that SACE_2467 overexpression might consume more ATP to transport cations, subsequently decreasing erythromycin production. α-ketoglutarate (α-KG), an intermediate of the tricarboxylic … Webbiosynthesis of erythromycin. However, the phosphoenolpyruvate node appears rigid and addition of PEP was excreted as 7-O-rhamnosyl flaviolin (red pigment). The ratio of the rate of carbon source consumption and oxygen uptake was concluded to be a critical parameter in the biosynthesis of erythromycin.
