Abstract

A two-plasmid mutagenesis system for Clostridioides difficile is described that improves ease of use and efficiency in creating site-directed mutations. pJB06 contains a xylose-inducible gene, while the second plasmid (pJB07) encodes the corresponding guide RNA (gRNA) and regions of homology for repair of the introduced double-stranded DNA (dsDNA) breaks, both of which are replaceable via restriction digest.

摘要

本文描述了一种用于艰难梭菌的双质粒诱变系统,该系统提高了创建定点突变的易用性和效率。pJB06包含一个木糖诱导型基因,而第二个质粒(pJB07)编码相应的引导RNA(gRNA)和用于修复引入的双链DNA(dsDNA)断裂的同源区域,这两者均可通过限制性酶切进行替换。
