Overview

Kanamycin sulfate is an aminoglycoside antibiotic, available in both oral and intravenous forms, and used to treat a wide variety ofinfections. Kanamycin is isolated from Streptomyces kanamyceticus.

Mechanism of Action

Pharmacology

Kanamycin works by affecting the 30S ribosomal subunit and causing a frameshift mutation or it prevents the translation of RNA. This means that instead of a codon CAT (for example in sequence CATG), a codon ATG is read by aminoacyl tRNA (aa-tRNA). Aminoacyl tRNA is consequently carrying a different amino acid, because the anticodon on the aa-tRNA is different. The protein needed cannot be synthesized: depending on the site and severity of the frame shift, either a completely different protein is synthesized, or a protein similar to the one needed is synthesized, but is folded incorrectly. A bacterium is destroyed because it cannot produce any of its proteins correctly.

Because of over-usage of antibiotics many bacteria have developed a resistance against kanamycin, and, consequently, it is not used much anymore.

Side effects

Common side effects include changes in hearing (either hearing loss or ringing in the ears), toxicity to kidneys, and allergic reactions to the drug.

Use in Research

Genes encoding kanamycin resistance are commonly used as selectable markers in molecular biology.
