Three distinct multiresistant loci from enterobacterial plasmids each comprised an integron and an IS26-associated sequence. Sequence comparison suggested a common ancestral structure that derived from an IS26 insertion into the 5' conserved segment of an In4-type integron and evolved through acquisition of gene cassettes and IS26-mediated recruitment of additional resistance genes of diverse origin.
来自肠杆菌质粒的三个不同的多抗性基因座均包含一个整合子和一个与IS26相关的序列。序列比较表明,其具有一个共同的祖先结构,该结构源于IS26插入In4型整合子的5'保守区段,并通过获取基因盒以及IS26介导的多种来源的其他抗性基因的募集而进化。
