title: Specific binding of Escherichia coli ribosomal protein S1 to boxA transcriptional antiterminator RNA.
abstract: We show that ribosomal protein S1 specifically binds the boxA transcriptional antiterminator RNAs of bacteriophage lambda and the Escherichia coli ribosomal RNA operons. Although S1 competes with the NusB-S10 antitermination complex for binding to boxA, it does not affect antitermination by the lambda N protein in vitro, and its role, if any, in rRNA synthesis is still unknown.
