Interspecies regulation of the SOS response by the E. coli lexA+ gene |
|
| Authors: | S G Sedgwick P A Goodwin |
| Abstract: | A plasmid-encoded E. coli lexA+ gene was introduced into 6 species of Enterobacteria. Ultraviolet light-sensitization occurred in all species except P. rettgeri, and 4 organisms showed reduced inducibility of RecA-like proteins. The mechanism of lexA+ control of the SOS response therefore appears common to several species. |
