Additional vectors for PCR-based gene tagging in Saccharomyces cerevisiae and Schizosaccharomyces pombe using nourseothricin resistance. | LitMetric

AI Article Synopsis

Article Abstract

The one-step PCR-mediated technique used for modification of chromosomal loci is a powerful tool for functional analysis in yeast. Both Saccharomyces cerevisiae and Schizosaccharomyces pombe are amenable to this technique. However, the scarce availability of selectable markers for Sz. pombe hampers the easy use of this technique in this species. Here, we describe the construction of new vectors deriving from the pFA6a family, which are suitable for tagging in both yeasts owing to the presence of a nourseothricin-resistance cassette. These plasmids allow various gene manipulations at chromosomal loci, viz. N- and C-terminal tagging with 3HA (haemagglutinin) or 13Myc epitopes, GST (glutathione S-transferase), 4TAP (tandem affinity purification) and several GFP (green fluorescent protein) isoforms. For N-terminal modifications, the use of different promoters allows constitutive (PADH1) or regulatable (PGAL1) promoters for S. cerevisiae and derivatives of Pnmt1 for Sz. pombe expression.

The molecular basis of pH sensing by the human fungal pathogen TOK potassium channel.

Bioelectricity Laboratory, Department of Physiology and Biophysics, School of Medicine, University of California, Irvine, Irvine, CA 92697, USA.

Two-pore domain, outwardly rectifying potassium (TOK) channels are exclusively expressed in fungi. Human fungal pathogen TOK channels are potential antifungal targets, but TOK channel modulation in general is poorly understood. Here, we discovered that TOK (CaTOK) is regulated by extracellular pH, in contrast to TOK channels from other fungal species tested.

Sphingolipids are crucial components of cell membranes and serve as important signaling molecules. Ceramide, as the central hub of sphingolipid metabolism, plays a significant role in various biological processes, including the cell cycle, apoptosis, and cellular aging. Alterations in sphingolipid metabolism are implicated in cellular aging, however, the specific sphingolipid components and intrinsic mechanisms that mediate this process remain largely uncharacterized.

Most commercially available red wines undergo alcoholic fermentation by yeasts, followed by a second fermentation with the lactic acid bacteria once the initial process is complete. However, this traditional approach can encounter complications in specific scenarios. These situations pose risks such as stalled alcoholic fermentation or the growth of undesirable bacteria while the process remains incomplete, leaving residual sugars in the wine.

Ergothioneine (ERG), a rare natural thio-histidine derivative with potent antioxidant properties and diverse biological functions, is widely utilized in food processing, cosmetics, pharmaceuticals, and nutritional supplements. Current bioproduction methods for ERG primarily depend on fermenting edible mushrooms. However, with the advancement in synthetic biology, an increasing number of genetically engineered microbial hosts have been developed for ERG production, including , , and .

Med15 is a general transcriptional regulator and tail module subunit within the RNA Pol II mediator complex. The Med15 protein has a well-structured N-terminal KIX domain, three activator binding domains (ABDs) and several naturally variable polyglutamine (poly-Q) tracts (Q1, Q2, Q3) embedded in an intrinsically disordered central region, and a C-terminal mediator association domain (MAD). We investigated how the presence of ABDs and changes in length and composition of poly-Q tracts influences Med15 activity using phenotypic, gene expression, transcription factor interaction and phase separation assays of truncation, deletion, and synthetic alleles.
