Abstract

ABSTRACT We show that ribosomal protein S1 specifically binds the boxA transcriptional antiterminator RNAs of bacteriophage λ 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 λ N protein in vitro, and its role, if any, in rRNA synthesis is still unknown.
