RcsB-BglJ-mediated activation of Cascade operon does not induce the maturation of CRISPR RNAs in E. coli K12.

Abstract:

:Prokaryotic immunity against foreign nucleic acids mediated by clustered, regularly interspaced, short palindromic repeats (CRISPR) depends on the expression of the CRISPR-associated (Cas) proteins and the formation of small CRISPR RNAs (crRNAs). The crRNA-loaded Cas ribonucleoprotein complexes convey the specific recognition and inactivation of target nucleic acids. In E. coli K12, the maturation of crRNAs and the interference with target DNA is performed by the Cascade complex. The transcription of the Cascade operon is tightly repressed through H-NS-dependent inhibition of the Pcas promoter. Elevated levels of the LysR-type regulator LeuO induce the Pcas promoter and concomitantly activate the CRISPR-mediated immunity against phages. Here, we show that the Pcas promoter can also be induced by constitutive expression of the regulator BglJ. This activation is LeuO-dependent as heterodimers of BglJ and RcsB activate leuO transcription. Each transcription factor, LeuO or BglJ, induced the transcription of the Cascade genes to comparable amounts. However, the maturation of the crRNAs was activated in LeuO but not in BglJ-expressing cells. Studies on CRISPR promoter activities, transcript stabilities, crRNA processing and Cascade protein levels were performed to answer the question why crRNA maturation is defective in BglJ-expressing cells. Our results demonstrate that the activation of Cascade gene transcription is necessary but not sufficient to turn on the CRISPR-mediated immunity and suggest a more complex regulation of the type I-E CRISPR-Cas system in E. coli.
