Evidence that ribosomal protein S10 participates in control of transcription termination.

Abstract
The isolation of an Escherichia coli K-12 strain with a mutation, nusE71, that results in a change in ribosomal protein S10 is reported. Phage .lambda. fails to grow in hosts carrying the nusE71 mutation because the .lambda.N gene product is not active. The N product regulates phage gene expression by altering transcription complexes so that they can overcome termination barriers. A ribosomal protein is apparently involved in antitermination of transcription.
