The rise of antibiotic-resistant pathogens necessitates novel drug development. Engineering natural product biosynthesis pathways, like polyketide synthases, yields new antimicrobial compounds, offering hope against infectious diseases.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Drug Discovery

Background:

  • Antibiotic resistance in human pathogens poses a global health crisis.
  • Continuous development of new antibiotics is crucial to combat evolving resistance.
  • Natural products remain a vital source of structurally diverse compounds for drug screening.

Purpose of the Study:

  • To review the engineering of biosynthetic gene clusters for novel natural product synthesis.
  • To highlight the potential of protein engineering in polyketide synthases (PKS).
  • To demonstrate the high-yield production of a biologically active erythromycin derivative.

Main Methods:

  • Utilizing functional genomics to identify new antimicrobial drug targets.
  • Applying genetic engineering techniques to modify natural product biosynthetic pathways.
