NCIt definition : The sulfate salt of kanamycin, a naturally occurring aminoglycoside antibiotic with
antimicrobial property. Derived from Streptomyces kanamyceticus, kanamycin is an antibiotic
complex consisting of three components: kanamycin A, the major component (also usually
designated as kanamycin), and kanamycins B and C, the minor components. This agent
irreversibly binds to the bacterial 30S ribosomal subunit. Specifically, this antibiotic
is lodged between 16S rRNA and S12 protein within the 30S subunit. This leads to interference
with translational initiation complex, misreading of mRNA, thereby hampering protein
synthesis and resulting in bactericidal effect. Aminoglycosides are mostly ineffective
against anaerobic bacteria, fungi and viruses.;
