The ‘Pf’ bacteriophages of Pseudomonas aeruginosa play roles in biofilm formation and virulence. Here, the authors identify a prophage regulatory module, KKP (kinase-kinase-phosphatase), that controls virion production of co-resident Pf prophages and mediates host defense against diverse lytic phages.
