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

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

Genes encoding essential components of core cellular processes are typically highly conserved across eukaryotes. However, a small proportion of essential genes are highly taxonomically restricted; there appear to be no similar genes outside the genomes of highly related species. What

Targeted alteration of the genome lies at the heart of the exploitation of S. pombe as a model system. The rate of analysis is often determined by the efficiency with which a target locus can be manipulated. For most loci

Intracellular bacterial pathogens secrete a repertoire of effector proteins into host cells that are required to hijack cellular pathways and cause disease. Despite decades of research, the molecular functions of most bacterial effectors remain unclear. To address this gap, we

Degradation of mitochondria by selective autophagy, termed mitophagy, contributes to the control of mitochondrial quality. Bcl2-L-13 is a mammalian homolog of Atg32, which is an essential mitophagy receptor in yeast. However, the molecular machinery involved in Bcl2-L-13-mediated mitophagy remains to

Clathrin-mediated endocytosis is an essential cellular function in all eukaryotes that is driven by a self-assembled macromolecular machine of over 50 different proteins in tens to hundreds of copies. How these proteins are organized to produce endocytic vesicles with high precision
