title: Stability of 70S ribosomes in relation to misreading and antibacterial activity of aminoglycosides.
abstract: The anomeric aminoglycosides, RU 21886 and RU 23468, which both have a 2-deoxystreptamine residue, stabilize 70S ribosomes to similar extents at low magnesium ion concentrations. Only RU 21886, however, has marked antibacterial and bactericidal activity and gives rise to a high level of misreading in cell-free protein synthesizing systems. It would thus appear that the ability to stabilize the association of the two ribosomal subunits does not necessarily lead to errors in translation.
