Article Abstract
We report that in vivo increased acetylation of the repressed Saccharomyces cerevisiae ADH2 promoter chromatin, as obtained by disrupting the genes for the two deacetylases HDA1 and RPD3, destabilizes the structure of the TATA box-containing nucleosome. This acetylation-dependent chromatin remodeling is not sufficient to allow the binding of the TATA box-binding protein, but facilitates the recruitment of the transcriptional activator Adr1 and induces faster kinetics of mRNA accumulation when the cells are shifted to derepressing conditions.

With the day to day increase in energy consumption due to increase in urbanization production of bioethanol is highly in demand. At this point where the traditional methods are not able to suffice the demands due to its high cost and low productivity, new methods need to be developed. This review aims to understand the importance and the regulation of ADH2 in Saccharomyces cerevisiae because Adh2p is the only enzyme that initiates the reaction for the conversion of ethanol, the end product of fermentation to acetaldehyde.

Ethanol, glycerol, methanol, and acetate are sustainable carbon sources (SCSs) used as substrates for biochemical production. Cells are simultaneously exposed not to a single but multiple external stimuli. SCSs as substrates and co-substrates must be directed/redirected into fermentations.

Chymosin is an enzyme used to coagulate milk, in the cheese industry. This study aimed to increase recombinant production of the chymosin in Pichia pastoris by determining the optimum copy number and overproduction of a Protein Disulfide Isomerase (PpPDI) chaperon protein. Bos taurus chymosin was expressed under the control of a mutant ADH2 promoter.

Despite the prevalence and importance of glycoproteins in human biology, methods for isotope labeling suffer significant limitations. Common prokaryotic platforms do not produce mammalian post-translation modifications that are essential to the function of many human glycoproteins, including immunoglobulin G1 (IgG1). Mammalian expression systems require complex media and thus introduce significant costs to achieve uniform labeling.

Hypoxia-inducible promoters of a wide range of activities are desirable for fine-tuning gene expression in response to oxygen limitation, especially for the Crabtree negative yeast Pichia pastoris (Komagataella phaffii) with a high oxygen consumption rate in large-scale fermentations. Here we constructed a hypoxia-inducible promoter library for P. pastoris through error-prone PCR of Pichia stipitis ADH2 promoter (Ps).
