Beschreibung

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

Wirkungsweise: Spectinomycin wirkt durch Hemmung der Proteinsynthese und -verlängerung, indem es an die bakterielle 30S-Ribosomen-Untereinheit bindet und in die Peptidyl-tRNA-Translokation eingreift.

Resistenzmethode: Eine Mutation in rpsE, dem Gen für das ribosomale Protein S5, verhindert die Bindung von Spectinomycin. Resistenz erfolgt auch durch das Aminoglykosid-3-′-Adenyltransferase-Gen (aadA).

Antimikrobielles Spektrum: Spectinomycin wirkt gegen gramnegative und grampositive Bakterien.
