Creation of an endA mutant strain in Pseudomonas aeruginosa PAO1 using gene replacement
Endonuclease I is an enzyme encoded by the endA gene. This nuclease degrades double stranded DNA. Many Escherichia coli common laboratory strains contain a mutation in the endA gene that inactivates the DNA-specific endonuclease I. A mutation in this gene greatly increases plasmid DNA yields in such E. coli strains as well as improves the quality of DNA that is isolated. The purpose of this research is to create an endA mutant strain in Pseudomonas aeruginosa PAO1 using gene replacement, thereby leading to the development of a useful laboratory Pseudomonas strain for use as a cloning strain. ...
