The fluxes through glycolytic enzymes in Saccharomyces cerevisiae are predominantly regulated at posttranscriptional levels

Metabolic fluxes may be regulated ‘‘hierarchically,’’ e.g., by changes of gene expression that adjust enzyme capacities (Vmax) and/or ‘‘metabolically’’ by interactions of enzymes with substrates, products, or allosteric effectors. In the present study, a method is developed to dissect the hierarchical regulation into contributions by...

Similar temperature dependencies of glycolytic enzymes: An evolutionary adaptation to temperature dynamics?

Background Temperature strongly affects microbial growth, and many microorganisms have to deal with temperature fluctuations in their natural environment. To understand regulation strategies that underlie microbial temperature responses and adaptation, we studied glycolytic pathway kinetics in Saccharomyces cerevisiae during temperature changes....

Control of the Glycolytic Flux in Saccharomyces cerevisiae Grown at Low Temperature: A multi-level analysis in anaerobic chemostat cultures

Growth-rate dependency of de novo resveratrol production in chemostat cultures of an engineered Saccharomyces cerevisiae strain

Introduction: Saccharomyces cerevisiae has become a popular host for production of non-native compounds. The metabolic pathways involved generally require a net input of energy. To maximize the ATP yield on sugar in S. cerevisiae, industrial cultivation is typically performed in aerobic, sugar-limited fed-batch reactors which, due to constraints...
