Description

General description

Chemical structure: aminoglycoside

Application

Spectinomycin is an aminocyclitol antibiotic derived from Streptomyces spectabilis. It has been shown to have a wide variety of uses, including treating acute gonorrheal urethritis and cervictis, to mark cell layers to monitor cell fate during leaf development, as a selection marker in plant related transformation systems for plant cells containing the marker gene Spcr, to study respiratory tract infections of cattle caused by Pasteurella multocida and Mannheimia haemolytica, and to generate plants deficient for the plastid-encoded RNA polymerase on MS-agar media. Spectinomycin also has use in amplification of low copy number plasmid carrying replicons. It is recommended for use in cell culture applications at 7.5-20 mg/L.

Biochem/physiol Actions

Mode d′action : La spectinomycine agit en inhibant la synthèse et l′allongement des protéines, en se liant à la sous-unité ribosomale 30S bactérienne et en interférant avec la translocation du peptidyl-ARNt.

Mode de résistance : Une mutation de rpsE, le gène de la protéine ribosomale S5, empêche la liaison de la spectinomycine. Une résistance est également conférée par le gène de l′aminoglycoside-3′-adényltransférase (aadA).

Spectre antimicrobien : La spectinomycine est efficace sur les bactéries à Gram positif et à Gram négatif.
