Abstract
Cells of Escherichia coli K-12 carrying lexA or recA mutations are more sensitive to UV radiation than corresponding wild-type cells and are defective in postreplication repair. Supressor mutations (tsl) have been described previously which increase the UV resistance of lexA uvr+, lexA uvrA, and recAI uvr+ strains, but not the resistance of recA1 uvrA strains. We have studied the effect of the tsl-1 mutation on postreplication repair and find that the enhanced survival conferred by this mutation is correlated with an increased capacity for postreplication repair.
摘要
携带lexA或recA突变的大肠杆菌K-12细胞比相应的野生型细胞对紫外线辐射更敏感，并且在复制后修复方面存在缺陷。先前已经描述了抑制突变（tsl），其增加了lexA uvr +、lexA uvrA和recA1 uvr +菌株的紫外线抗性，但没有增加recA1 uvrA菌株的抗性。我们研究了tsl-1突变对复制后修复的影响，发现该突变赋予的增强存活率与复制后修复能力的增加相关。
