As an aminoglycoside antibiotic, tobramycin is active against aerobic gram-negative bacteria, including Pseudomonas aeruginosa. Tobramycin binds to the 16s ribosomal RNA component of the bacterial 30s ribosomal unit, inhibiting the initiation step of translation. By binding to the A-site, tobramycin induces mistranslation and causes transfer RNA to misread the codon, thus causing incorrect delivery of aminoacyl units. Incorrectly synthesized proteins build up inside the cell, disrupting the cell membrane and various cellular processes; this mechanism of action designates tobramycin as a bactericidal agent.
