Abstract:
Protein synthesis was studied in polyamine-auxotrophic mutants of E. coli. The decreased protein synthesizing rate observed both in vivo and in vitro in polyamine-starved bacteria is due to defective 30S ribosomal subparticles which are impaired in the initiation step of translation. Analysis of peptides synthesized in vivo suggests a more extensive misreading by putrescine-depleted bacteria. Cells grown without polyamine show a markedly decreased response to the inhibitory effect and the misreading inducing action of streptomycin in vivo and in vitro. The polyamine-starved bacteria are also less sensitive to other aminoglycoside antibiotics such as neomycin, kanamycin and kasugamycin.
