gene mutation through CRISPR RNA-guided base editing weakens bacterial virulence and immune evasion.

The resistance of commonly used clinical antibiotics, such as daptomycin (DAP), has become increasingly serious in the fight against () infection. It is essential to explore key pathogenicity-driven genes/proteins in bacterial infection and antibiotics resistance, which contributes to develop novel therapeutic strategies against infections. The gene of , encoding 5'-nucleotidase (NT5), is nearly unknown for its function in drug resistance and bacterial infection.

CRISETR: an efficient technology for multiplexed refactoring of biosynthetic gene clusters.

The efficient refactoring of natural product biosynthetic gene clusters (BGCs) for activating silent BGCs is a central challenge for the discovery of new bioactive natural products. Herein, we have developed a simple and robust CRISETR (CRISPR/Cas9 and RecET-mediated Refactoring) technique, combining clustered regulatory interspaced short palindromic repeats (CRISPR)/Cas9 and RecET, for the multiplexed refactoring of natural product BGCs. By this approach, natural product BGCs can be refactored through the synergistic interaction between RecET-mediated efficient homologous recombination and the CRISPR/Cas9 system.
