The bacteriophage lambda N protein regulates phage development by selectively suppressing transcription termination in its host, Escherichia coli. The E. coli nus mutants prevent N activity. To provide additional information on transcription termination, we have isolated pseudo-revertants of the nusA1 mutation that restore lambda N function. One series of pseudo-revertants lie in the E. coli nusB gene, whose product is normally required for lambda N activity. These mutations are N-specific… CONTINUE READING
