LexA - a repressor for LexA-regulated SOS promoters -

Escherichia coli and other organisms have a gene cluster activated in case of emergency, which is called "SOS genes". It is well-documented that in E. coli, most of those SOS genes are repressed by LexA protein. When the cell is exposed to excess stress, RecA is up-produced, which promotes the self-degradation of LexA. As a result, many LexA-regulated genes become expressed. Combined with RecA and SOS promoters (for instance, recAp and sulAp), a stress-responsive gene-expression circuit was assembled.
