Numerous mechanisms at the level of transcription and posttranscriptionally ensure that colicins are produced only in cells exposed to extreme stress such as DNA damage and starvation.
COBISS.SI-ID: 2687055
Analysis of resistence agaisnt colicins and virulence factors of pathogenic as well as commensal Escherichia coli strains revealed their correlation.
COBISS.SI-ID: 2552399
Repressors LexA and IscR inhibit expression of the colicin K gene, cka. iscR stabilizes lexA binding to operator sequences and provokes a delay in cka exčpression following DNA damage providing bacterial cells time to repair DNA damage.
