(Submitter supplied) Global transcription machinery engineering (gTME) is an approach for reprogramming gene transcription to elicit cellular phenotypes important for technological applications. Here we show the application of gTME to Saccharomyces cerevisiae for improved glucose/ethanol tolerance, a key trait for many biofuels programs. Mutagenesis of the transcription factor Spt15p and selection led to dominant mutations that conferred increased tolerance and more efficient glucose conversion to ethanol. more...

(Submitter supplied) Purpose: We want to know whether MINC(Mot1-Ino80C-NC2) suppress pervasive transcription at both euchromatin and heterochromatin Using next generation sequencing we show that Mot1, Ino80 chromatin remodeling complex (Ino80C), and NC2 (MINC) colocalize on chromatin and cooperate to suppress pervasive transcription in S. cerevisiae and murine embryonic stem cells (mESCs). Conclusion: Our ChIP-Seq and mRNA-Seq data show that MINC regulates pervasive transcription in yeast and mammals

(Submitter supplied) Previous studies suggested that expression of most yeast mRNAs is dominated by either transcription factor TFIID or SAGA. We reexamined this longstanding problem by rapid depletion of TFIID subunits and measurement of changes in nascent transcription. We find that transcription of nearly all mRNAs is strongly dependent on TFIID function. Degron-dependent depletion of Tafs 1,2,7,11, and 13 showed similar transcription decreases for genes in the Taf1-depleted, Taf1-enriched, TATA-containing and TATA-less gene classes. more...

(Submitter supplied) RNA Pol II transcription has been implied to be either regulated by the general transcription factor TFIID or the co-activator SAGA. Also, this dominancy of either SAGA or TFIID might be according to the existance, or not, of a TATA consensus sequence. We used microarrays to analyse newly-synthesized RNA in two mutants that allow conditional nuclear depletion of Taf4 or Taf5 to reevaluate whether some genes are more affected than others.

(Submitter supplied) Rsf1p is a putative transcription factor required for efficient growth using glycerol as sole carbon source but not for growth on the alternative respiratory carbon source ethanol. We use microarrays to determine the differences in the transcriptional program between the Δrsf1 mutant and the wild type during respiratory growth on glycerol as well as the transition to growth on glycerol as sole carbon source. more...

(Submitter supplied) The engineering of Saccharomyces cerevisiae strains for lactose utilization has been attempted with the intent of developing high productivity processes for alcoholic fermentation of cheese whey. A recombinant S. cerevisiae flocculent strain that efficiently ferments lactose to ethanol was previously obtained by evolutionary engineering of an original recombinant that displayed poor lactose fermentation performance. more...

(Submitter supplied) The SAGA complex of Saccharomyces cerevisiae contains greater than 20 components that acetylate and deubiquitylate nucleosomal histones. Its acetyltransferase, Gcn5 preferentially acetylates histones H3 and H2B and is regulated through interactions with Ada2 and Ngg1/Ada3. The N-terminal region of Ada2 contains a SANT domain that contacts Gcn5 near its catalytic site. Sequence alignments of Ada2 homologues indicate a conserved ~120 amino acid residue central region that interacts with Ngg1.To examine the function of this central region, we constructed ada2 alleles with mutations of clustered conserved residues. more...

(Submitter supplied) In this study, using DNA microarray analysis, we compared the comprehensive expression profiles of two yeast trains, i.e, the previously obtained ethanol-adapted yeast strain and the parental strain as control (FY834), under the ethanol stress condition (YPD medium contained 10% ethanol). As a result, we identified certain genes and functional categories of the genes that are possible involved in growth under the ethanol stress condition.

(Submitter supplied) We aimed to explore the application of the Target-AID base editor in genomic in situ protein engineering by generating nonsynonymous mutations. A general transcription factor Spt15 (TATA-box binding protein) gene of Saccharomyces cerevisiae was selected as a target. Based on computational and experimental scanning mutagenesis of the Spt15 gene as well as flask-fermentation screening, three stress-tolerant Spt15 mutant strains (A140G, P169A and R238K) and two stress-sensitive Spt15 mutant strains (S118L and L214V) were obtained. more...
