Abstract excerpt
Previous work in this laboratory has shown that heat shock or vitamin B1 deprivation induces an error-free DNA-repair process in Escherichia coli. The system is absolutely dependent on excision repair, while its induction is delayed in lon- or recA- cells. We have now shown that starvation of E. coli for amino acids, glucose or phosphate, conditions known to induce the stringent response or the glu and pho...
