Creation of New Metabolic Pathways or Improvement of Existing Metabolic Enzymes by In Vivo Evolution in Escherichia coli
A method for in vivo evolution of metabolic pathways in bacteria is described. This method is a powerful tool for synthetic biology type of metabolic design and can lead to the creation of new metabolic pathways or the improvement of existing metabolic enzymes. The proposed strategy also permits to relate the evolved phenotype to the genotype and to analyze evolution phenomenon at the genetic, biochemical, and metabolic levels.
