Termination of transcription by nusA gene protein of Escherichia coli.

The nusA gene protein of Escherichia coli and N gene protein of bacteriophage lambda interact in vitro and cooperate in vivo to prevent transcription termination. In vitro the nusA gene protein causes RNA polymerase to pause in the tR2 terminator region of lambda DNA. A completed termination event at tR2 requires both the nusA gene protein and the previously described E. coli termination factor rho. The nusA gene protein is therefore both a transcription termination factor and a protein which couples antitermination factors to the elongating transcription complex.[1]
