Minimizing acetate formation in E. coli fermentations [PDF]
, 2007 Escherichia coli remains the best established production organisms in industrial biotechnology. However, during aerobic fermentation runs at high growth rates, considerable amounts of acetate are accumulated as by-product.

The Metabolic Fates of Pyruvate in Normal and Neoplastic Cells
Cells, 2021 Pyruvate occupies a central metabolic node by virtue of its position at the crossroads of glycolysis and the tricarboxylic acid (TCA) cycle and its production and fate being governed by numerous cell-intrinsic and extrinsic factors.

The Urea Carboxylase and Allophanate Hydrolase Activities of Urea Amidolyase Are Functionally Independent [PDF]
, 2016 Urea amidolyase (UAL) is a multifunctional biotin-dependent enzyme that contributes to both bacterial and fungal pathogenicity by catalyzing the ATP-dependent cleavage of urea into ammonia and CO2.

Frontiers in Bioengineering and Biotechnology, 2021 Wild-type C. glutamicum ATCC 13032 is known to possess two enzymes with anaplerotic (C4-directed) carboxylation activity, namely phosphoenolpyruvate carboxylase (PEPCx) and pyruvate carboxylase (PCx). On the other hand, C3-directed decarboxylation can be

Bonded Cumomer Analysis of Human Melanoma Metabolism Monitored by 13C NMR Spectroscopy of Perfused Tumor Cells. [PDF]
, 2015 A network model for the determination of tumor metabolic fluxes from (13)C NMR kinetic isotopomer data has been developed and validated with perfused human DB-1 melanoma cells carrying the BRAF V600E mutation, which promotes oxidative metabolism.

My favorite pyruvate carboxylase [PDF]
IUBMB Life, 2010 Having completed a PhD in molecular and cellular biology in mammalian reproduction at the University of Sydney, my first postdoctoral appointment began early in 1965 in the laboratory of Sir Hans Krebs at Oxford University where I had the pleasure of working with Dr Eric Newsholme on the regulation of gluconeogenesis and glycolysis during fetal ...

A distinct holoenzyme organization for two-subunit pyruvate carboxylase
Nature Communications, 2016 Pyruvate carboxylases are homotetrameric enzymes in eukaryotes and most bacteria. Here, the authors report the structure of an unusual two-subunit form of the enzyme from the Gram-negative bacterium Methylobacillus flagellates, revealing an unexpected ...
