Neomycin is an aminoglycoside antibiotic and has a bactericidal action
against many gram-negative bacteria. Aminoglycosides are taken up into
sensitive bacterial cells by an active transport proces. Within the cell they
bind to the 30S and to some extent to the 50S subunits of the bacterial
ribosome, inhibiting protein synthesis and generating errors in the transcripton
of the genetic code. Neomycin is used as a selective agent for the
incorporation of the NPT II (APH3’) gene in plant tissue.
