Nourseothricin - Powder

Nourseothricin is a mixture of streptothricins C, D, E, and F and can be used as a selection antibiotic for a broad spectrum of prokaryotic and eukaryotic organisms (i.e., Gram-positive and Gram-negative bacteria, yeast, filamentous fungi, protozoa, microalgae, plants, and many more). Selection of recombinant strains is based on the inactivation of nourseothricin by mono-acetylation of the beta-amino group of the beta-lysine residue by nourseothricin N-acetyltransferase, the product of the sat1 or nat1 genes.
