Polynucleotide phosphorylase of Escherichia coli is required for the establishment of bacteriophage P4 immunity.

Journal of bacteriology - 1 Sept 1996

Piazza F, Zappone M, Sana M, Briani F, Dehò G

Abstract excerpt

Bacteriophage P4's superinfection immunity mechanism is unique among those of other known bacteriophages in several respects: (i) the P4 immunity factor is not a protein but a short, stable RNA (CI RNA); (ii) in the prophage the expression of the replication operon is prevented by premature transcription termination rather than by repression of transcription initiation; (iii) transcription termination is...
