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

Our ability to understand the genotype-to-phenotype relationship is hindered by the lack of detailed understanding of phenotypes at a single-cell level. To systematically assess cell-to-cell phenotypic variability, we combined automated yeast genetics, high-content screening and neural network-based image analysis of

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

An important but still enigmatic function of DNA:RNA hybrids is their role in DNA double-strand break (DSB) repair. Here, we show that Sen1, the budding yeast ortholog of the human helicase Senataxin, is recruited at an HO endonuclease-induced DSB and

O-mannosylation is implicated in protein quality control in Saccharomyces cerevisiae due to the attachment of mannose to serine and threonine residues of un- or misfolded proteins in the endoplasmic reticulum (ER). This process also designated as unfolded protein O-mannosylation (UPOM)
