Tobramycin, an aminoglycoside antibiotic obtained from cultures of Streptomyces tenebrarius, is used in combination with other antibiotics to treat urinary tract infections, gynecologic infections, peritonitis, endocarditis, pneumonia, bacteremia and sepsis, respiratory infections including those associated with cystic fibrosis, osteomyelitis, and diabetic foot and other soft-tissue infections. It acts primarily by disrupting protein synthesis, leading to altered cell membrane permeability, progressive disruption of the cell envelope, and eventual cell death. Tobramycin has in vitro activity against a wide range of gram-negative organisms including Pseudomonas aeruginosa.

Mechanism of action

Tobramycin binds irreversibly to one of two aminoglycoside binding sites on the 30 S ribosomal subunit, inhibiting bacterial protein synthesis. Tobramycin may also destabilize bacterial memebrane by binding to 16 S 16 S r-RNA. An active transport mechanism for aminoglycoside uptake is necessary in the bacteria in order to attain a significant intracellular concentration of tobramycin.

Enteric bacteria and other eubacteria

The bioavailability of tobramycin may vary because of individual differences in nebulizer performance and airway pathology.

Pharmacological action
In prokaryotes, the 16S rRNA is essential for recognizing the 5' end of mRNA and hence positioning it correctly on the ribosome. The 16S rRNA has a characteristic secondary structure in which half of the nucleotides are base-paired. The 16S rRNA sequence has been highly conserved and is often used for evolutionary and species comparative analysis.

Mycobacterium tuberculosis
Pharmacological action
General Function
May catalyze the coenzyme A-dependent acetylation of the 2' hydroxyl or amino group of a broad spectrum of aminoglycosides and confer resistance to aminoglycosides (By similarity). In vitro assays show no significant increase of resistance to aminoglycosides, possibly due to low expression in a heterologous system (PubMed:9159528).
Specific Function
Aminoglycoside 2'-n-acetyltransferase activity
Gene Name
Uniprot ID
Uniprot Name
Aminoglycoside 2'-N-acetyltransferase
Molecular Weight
20037.53 Da
