TL;DR: The intracellular carbon flux distribution in wild-type and pyruvate kinase-deficient Escherichia coli was estimated using biosynthetically directed fractional 13C labeling experiments with [U-13C6]glucose, two-dimensional nuclear magnetic resonance (NMR) spectroscopy of cellular amino acids, and a comprehensive isotopomer model.
Journal ArticleDOI
Application of mathematical tools for metabolic design of microbial ethanol production.
TL;DR: Experiments and calculations suggest that, in resting Escherichia coli cells, ethanol production and glucose uptake rates can be increased by 30% and 20%, respectively, by overexpression of a deregulated pyruvate kinase, while increase in phosphofructokinase expression levels has no effect on ethanol production
Journal ArticleDOI
Glucose catabolism of Escherichia coli strains with increased activity and altered regulation of key glycolytic enzymes.
TL;DR: The flux data demonstrate that overexpression of even single enzymes early in a central pathway can increase the fluxes to a particular metabolic product, although it may not affect the glucose uptake rate.
Journal ArticleDOI
Altered regulation of pyruvate kinase or co-overexpression of phosphofructokinase increases glycolytic fluxes in resting Escherichia coli.
TL;DR: It is concluded that glycolytic fluxes in E. coli with submaximal (aerobic) metabolic activity can be increased by overexpression of pyruvate kinases which do not require allosteric activation or co-overexpression with Pfk, however, such improvements require more extensive engineering.
