Defective 30S ribosomal particles in a polyamine auxotroph of Escherichia coli

Polypeptide synthesis directed by poly(U) or MS 2 phage RNA is several fold more active in cell-free systems prepared from polyamine supplemented bacteria than in extracts of polyamine depleted cells. This effect depends on the presence of defective 30S ribosomal subunits in the starved bacteria. It...
