A process of bacterial RNA polymerase wherein it is resistant to pause, arrest, or termination signals. It is an important control mechanism in the reproduction of some bacteriophages.

antitermination

a process in which RNA POLYMERASE does not recognize a normal TRANSCRIPTION termination signal at the end of a GENE or OPERON during transcription and so transcribes the DNA beyond the terminator. Antitermination provides a means of regulating the EXPRESSION of genes.

Cleavage of cI enables transcription of the phage antiterminator Q, which activates the late phage genes, including stx (25).
The antiterminator Q gene of bacteriophage 933W ([Q.
