General description
Chemical structure: peptidyl nucleoside
Application
Noursethricin is used as a dominant selection antibiotic for genetically modified bacteria, yeasts, fungi, protozoa and plants.
Biochem/physiol Actions
Antifungal effective against Candida albicans. Candida species transformed with the gene encoding nourseothricin acetyltransferase (CaNAT1) were resistant to nourseothricin.
Nourseothricin inhibits biosynthesis and induces miscoding. Resistance to nourseothricin is mediated by the sat1 encoded N-acetyltransferase. Nourseothricin is inactivated by acetylation of the β-amino group of the β-lysin.
