Using an in vitro preparation for protein synthesis, we have studied the effect of the ribosomal protein S1 from Escherichia coli on the synthesis of the coat protein of the RNA-containing phages Qbeta and MS2, on that of an "early" and a "late" enzyme encoded by the DNA containing phage T7, and on that of anthranilate synthetase, an enzyme encoded by the bacterial tryptophan operon. Our results indicate that for the synthesis of these five proteins the presence of S1 is required. From these results we conclude that S1 is an essential protein for the translation of bacterial and bacteriophage messenger RNA.
