Binding of streptomycin also destabilizes a tertiary interaction between 16S rRNA helices 44 and 45 . Streptomycin is in position to contact several lysine ε-amino groups of ribosomal protein S12, including K42, K43, and K87 ( 8 ), and resistance is frequently conferred by amino acid substitutions at any one of these positions ( 30 – 32 ).

Stereospecificity of Aminoglycoside Ribosomal Interactions
In vitro selection and characterization of streptomycin
Several lines of evidence indicate that the universally conserved 530 loop of 16S ribosomal RNA plays a crucial role in translation, related to the binding of tRNA to the ribosomal A site.
Interactions between Viomycin Resistance and Streptomycin
The drug wedges into one of the ribosomal RNA helices at the site where the mRNA is matched with the appropriate tRNA, blocking the subtle motions needed for decoding and translocation. The second site is on the large ribosomal subunit, binding to a small loop of ribosomal RNA that interacts with ribosomal recycling factor (RRF), the protein that assists the recycling of ribosomes.

In cells, the interaction between RNA and proteins can be measured using reporter gene fusion 105. Moreover, a novel method to identify new compounds that disrupt the function of ribosomes in Mycobacterium tuberculosis 106 has identified two compounds (T766 and T054) with potent specific activity against M. tuberculosis and low toxicity to mice and other bacterial strains.
