SPECIFIC BINDING OF ESCHERICHIA-COLI RIBOSOMAL-PROTEIN S1 TO BOXA TRANSCRIPTIONAL ANTITERMINATOR RNA

We show that ribosomal protein S1 specifically binds the boxA transcri ptional antiterminator RNAs of bacteriophage lambda and the Escherichi a coli ribosomal RNA operons, Although S1 competes with the NusB-S10 a ntitermination complex for binding to boxA, it does not affect antiter mination by the lambda N protein in vitro, and its role, if any, in rR NA synthesis is still unknown.
