Two overlapping SOS-boxes in ColE operons are responsible for the viability of cells harboring the Col plasmid.

Molecular & general genetics : MGG - 24 Jun 1996

Lu F M, Chak K F

Abstract excerpt

In this study, oligonucleotide-directed site-specific mutagenesis was used to change the consensus sequences of the LexA binding motifs in either one of the two SOS-boxes of the ColE7 operon. The results indicated that both mutants produced larger amounts of colicin than cells harboring the wild-type ColE7 plasmid. This finding would imply that two biologically functional SOS boxes exist in the ColE7 operon. In...
