The identification of the KinB–AlgB two-component system, known to modulate alginate biosynthesis, together with downstream proteins that repress the Type I-F CRISPR–Cas system in Pseudomonas aeruginosa, elucidates how bacteria control the expression of nucleolytic host defence systems to minimize the potential risks of self-targeting.
