Cleavage of the 246 bp palindrome by SbcCD induces the SOS response.
Fluorescence distribution profiles of average Gray value in pixels of populations of sbcDC+ or ΔsbcDC cells containing or not the chromosomal 246 bp interrupted palindrome (PAL) and carrying a plasmid encoding a PsfiA-gfp fusion (pGB150). Error bars show the standard error of the mean of 4 independent experiments investigating 350 cells each. (A) In a wild-type background. (B) In a ΔslmA background.
