Abstract
We have isolated and characterized extragenic suppressors of mutations in two different target genes that affect DNA replication in Salmonella typhimurium. Both the target and the suppressor genes are functional homologues of known replication genes of E. coli that were identified in intergeneric complementation tests. Our results point to interactions in vivo involving the dnaB and dnaC proteins in one case and the dnaQ and dnaE proteins in the other case. The suppressor mutations, which were isolated as derivatives of lambda-Salmonella in vitro recombinants, were detected by an adaptation of the red plaque complementation assay. This method was applicable even when the locus of suppressor mutations was not chosen in advance.
摘要
我们已经分离并鉴定了影响鼠伤寒沙门氏菌DNA复制的两个不同靶基因的基因外抑制子。靶基因和抑制子基因都是大肠杆菌已知复制基因的功能同源物，这些同源物是在属间互补试验中鉴定出来的。我们的结果表明，在一种情况下，体内存在涉及dnaB和dnaC蛋白的相互作用；在另一种情况下，存在涉及dnaQ和dnaE蛋白的相互作用。这些抑制子突变是作为λ-沙门氏菌体外重组体的衍生物分离出来的，通过改进的红斑互补试验进行检测。即使抑制子突变的位点没有预先选定，这种方法也适用。
