Received 25 January 2002/ Accepted 24 March 2002

Transcription antitermination by the bacteriophage {lambda} N protein is stimulated in vitro by the Escherichia coli NusG protein. Earlier work suggested that NusG was not required for N activity in vivo. Here we present evidence that NusG also stimulates N-mediated transcription antitermination in intact cells.
