Abstract:
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 is concluded that polyamines play a role in the normal biosynthesis, maturation and/or assembly of the small ribosomal subparticles. © 1975.
