NCIt definition : A semisynthetic, water soluble aminoglycoside derived from sisomicin, a naturally
occurring antibiotic produced by the fermentation of Micromonospora inyoensis. Netilmicin
irreversibly binds to the 16S rRNA and S12 protein of the bacterial 30S ribosomal
subunit. As a result, this agent interferes with the assembly of initiation complex
between mRNA and the bacterial ribosome, thereby inhibiting the initiation of protein
synthesis. In addition, netilmicin induces misreading of the mRNA template and causes
translational frameshift, thereby results in premature termination. This eventually
leads to bacterial cell death.;
