Abstract
We developed a negative counterselection system for Pseudomonas putida based on uracil phosphoribosyltransferase (UPRTase) and sensitivity against the antimetabolite 5-fluorouracil (5-FU). We constructed a P. putida strain that is resistant to 5-FU and constructed vectors for the deletion of the surface adhesion protein gene, the flagellum biosynthesis operon, and two endonuclease genes. The genes were efficiently disrupted and left a markerless chromosomal in-frame deletion.Entities:
