The ampicillin resistance locus of three different ampicillin-resistant, temperature-sensitive Escherichia coli mutants was mapped between proC and purE and does not correspond to any of the known genes in this region. The mutant gene responsible for the temperature sensitivity and consequent morphological changes in each mutant strain was not located in the same 5-min region, even though the two mutants characteristics co-reverted at a very high frequency.
三种不同的氨苄青霉素抗性、温度敏感型大肠杆菌突变体的氨苄青霉素抗性位点被定位在proC和purE之间,且与该区域的任何已知基因均不对应。尽管两种突变体特征以非常高的频率共同回复突变,但负责每个突变菌株温度敏感性及随之而来的形态变化的突变基因并不位于同一个5分钟区域。
