NCIt definition : An aminoglycoside antibiotic derived from Streptomyces tenebrarius with bacteriostatic
activity. Following active transport into the cell, tobramycin binds irreversibly
to a specific aminoglycoside receptor on the bacterial 30S ribosomal subunit and interferes
with the initiation complex between messenger RNA and the 30S subunit, thereby inhibiting
initiation of protein synthesis, consequently leading to bacterial cell death. In
addition, tobramycin induces misreading of the mRNA template causing incorrect amino
acids to be incorporated into the growing polypeptide chain, consequently interfering
with protein elongation.;
