Abstract
The nusA gene protein of Escherichia coli and N gene protein of bacteriophage γ 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 γ 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.
