Saccharomyces cerevisiae
Food MicrobiologySaccharomyces cerevisiae Cytosolic Thioredoxins Control Glycolysis, Lipid Metabolism, and Protein Biosynthesis under Wine-Making ConditionsOxidative stress is a common hazardous condition that cells have to face in their lifetime. Oxidative damage may diminish cell vitality and viability by reducing metabolism and eventually leading to aging and ultimate death. Wine yeast Saccharomyces cerevisiae also faces oxidative attack during its biotechnological uses. One of the main yeast antioxidant systems...
BiotechnologyPrimary and Secondary Metabolic Effects of a Key Gene Deletion (ΔYPL062W) in Metabolically Engineered Terpenoid-Producing Saccharomyces cerevisiaeAlthough computational and reverse metabolic engineering approaches often lead to improved gene deletion mutants for cell factory engineering, the systems level effects of such gene deletions on the production phenotypes have not been extensively studied. Understanding the genetic and molecular function of such gene alterations on production strains will minimize the risk inherent in the development of large-scale fermentation processes...
Food MicrobiologyNutrient Signaling via the TORC1-Greatwall-PP2AB55δ Pathway Is Responsible for the High Initial Rates of Alcoholic Fermentation in Sake Yeast Strains of Saccharomyces cerevisiaeThe biochemical processes and enzymes responsible for glycolysis and alcoholic fermentation by the yeast S. cerevisiae have long been the subject of scientific research. Nevertheless, the factors determining fermentation performance in vivo are not fully understood. As a result, the industrial breeding of yeast strains has required empirical characterization...
- Enzymology and Protein Engineering | SpotlightShuffling the Neutral Drift of Unspecific Peroxygenase in Saccharomyces cerevisiae
Fungal peroxygenases resemble the peroxide shunt pathway of cytochrome P450 monoxygenases, performing selective oxyfunctionalizations of unactivated C-H bonds in a broad range of organic compounds. In this study, we combined neutral genetic drift and in vivo DNA shuffling to generate highly functional peroxygenase mutant libraries. The panel of neutrally evolved peroxygenases showed different activity profiles for...
