RIBOSOMAL LOCALIZATION OF STREPTOMYCIN SENSITIVITY

Abstract
Streptomycin decreased the poly-uridylic-acid-dependent incorporation of C14-labeled phenylalanine into acid-insoluble products in a cell-free system containing ribosomes of streptomycin sensitive Escherichia coli and the supernatant of sensitive or resistant cells. There was no inhibition when the system contained ribosomes of streptomycin-resistant E. coli and supernant of either resistant or sensitive cells. The ribosomes are the site of streptomycin-sensitivity. The genetic locus is part of a ribosome-specific region of the bacterial chromosome.
