Transcripts that increase the processivity and elongation rate of RNA polymerase.

Abstract excerpt

Transcripts encoded by the cis-acting antitermination sites (put sites) of lambdoid phage HK022 promote readthrough of downstream transcription terminators. Proper conformation of the transcripts is essential for activity, since put mutations that prevent the formation of predicted RNA stems prevented antitermination, and suppressor mutations that restore the stems restored antitermination. Antitermination does...
