Colicin E3 Induced Cleavage of 16S rRNA of Isolated 30S Ribosomal Subunits1

Abstract

Contrary to the previous findings we found that a specific cleavage of 16S rRNA occurred when protein A, the active component of colicin E3, was interacted with isolated 30S ribosomal subunits at high concentrations. Necessary experiments to disprove the possibility of artefacts are described.
