Escherichia coli cells with the pcbA1 allele and temperature-sensitive DNA polymerase III mutations survived at a restrictive temperature if DNA polymerase I activity was present. The Klenow fragment of DNA polymerase I was capable of supporting cell survival as well.
携带pcbA1等位基因和温度敏感型DNA聚合酶III突变的大肠杆菌细胞,如果存在DNA聚合酶I活性,就能在限制温度下存活。DNA聚合酶I的克列诺片段也能够支持细胞存活。
