Abstract
Bacteriophage lambda N gene product acts to modify host RNA polymerase allowing the formation of a termination-resistant transcription apparatus. Previous studies have demonstrated that the nusE71 mutation that has altered the ribosomal protein S10 prevents N action in vivo. Using a coupled transcription-translation system, we demonstrate here that purified S10 protein as well as the 30S ribosomal subunit is sufficient to restore N activity in the nusE mutant extract, allowing antitermination of Rho-dependent and Rho-independent terminators. This provides direct biochemical evidence that the S10 protein itself is one of the cellular components necessary for the formation of an antitermination apparatus.This publication has 33 references indexed in Scilit:
