摘要：

The dinI homolog of S. marcescens was cloned from a plasmid library by virtue of its ability to inhibit nuclease expression from the S. marcescens nucA gene integrated in the genome of E. coli. The S. marcescens DinI protein is 68% identical to DinI of E. coli. It has a similar effect on other SOS regulated genes and likely exerts it effect on nuclease expression, which is most pronounced as the cells entered stationary phase, through inhibition of basal SOS expression.
