Specific binding of Escherichia coli ribosomal protein S1 to boxA transcriptional antiterminator RNA.
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.
