靶向突变是确定给定基因的功能及其参与细菌致病的主要工具之一。在分枝杆菌中,基因缺失通常通过使用等位基因交换技术来完成,该技术通常利用自杀递送载体。我们已经采用了广泛使用的自杀传递载体(p1NIL)的连接非依赖性克隆(LIC)克隆基因的两个侧翼区。生产的pNILRB质粒系列允许更快、更有效和更省力的克隆过程。在本文中,我们描述了制作pNILRB5,p1NIL的修改版本,包含两对LIC位点侧翼的sacB或lacZ基因。我们通过产生3种分枝杆菌突变株证明了这种技术的成功。这些载体将有助于更高通量的诱变方法。
Targeted mutagenesis is one of the major tools for determining the function of a given gene and its involvement in bacterial pathogenesis. In mycobacteria, gene deletion is often accomplished by using allelic exchange techniques that commonly utilise a suicide delivery vector. We have adapted a widely-used suicide delivery vector (p1NIL) for cloning two flanking regions of a gene using ligation independent cloning (LIC). The pNILRB plasmid series produced allow a faster, more efficient and less laborious cloning procedure. In this paper we describe the making of pNILRB5, a modified version of p1NIL that contains two pairs of LIC sites flanking either a sacB or a lacZ gene. We demonstrate the success of this technique by generating 3 mycobacterial mutant strains. These vectors will contribute to more high-throughput methods of mutagenesis.
