RESUMO
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.
