Overview

Randomized trial develops genetic tools to enhance biosynthetic pathways in myxobacteria, suggesting improved natural product discovery.

Key Points

  • The aim is to develop genetic toolkits for manipulating myxobacteria to enhance the discovery of bioactive compounds.
  • Constructed a heterologous expression chassis using Myxococcus xanthus DK1622.
  • Introduced MxRecET recombinases and TnpB nuclease for genome editing and manipulation.
  • Demonstrated efficient expression of four polyketide synthase biosynthetic gene clusters in engineered strains.
  • MxDIRECT technology allows seamless deletions of DNA fragments up to 200 kb.
  • Enhanced growth properties and increased robustness of the MxPKS chassis were achieved.
  • Multiple new polyketides were discovered through heterologous expression using the MxPKS platform.
