摘要：
The invention relates to the improvement of endonuclease-based antimicrobials by blocking DNA repair of double-strand break(s) (DSB(s)) in prokaryotic cells. In this respect, the invention especially concerns a method involving blocking DNA repair after a nucleic acid has been submitted to DSB, in particular by a Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) associated programmable double-strand endonuclease. The invention particularly relates to the use of an exogenous molecule that inhibits DNA repair, preferably a protein that binds to the ends of the double-stranded break to block DSB repair. The invention also relates to vectors, particularly phagemids and plasmids, comprising nucleic acids encoding nucleases and Gam proteins, and a pharmaceutical composition and a product containing these vectors and their application.
