Description

Biochem/physiol Actions

Antifungal effective against Candida albicans. Candida species transformed with the gene encoding nourseothricin acetyltransferase (CaNAT1) were resistant to nourseothricin.1

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.

Application

Noursethricin is used as a dominant selection antibiotic for genetically modified bacteria, yeasts, fungi, protozoa and plants.
