Xylitol dehydrogenase fromPachysolen tannophilus

FEMS Microbiology Letters, 1984
NAD-xylitol-dehydrogenase (EC 1.1.1.9) from Pachysolen tannophilus was investigated in relation to xylitol byproduction during xylose fermentation by this yeast. For this purpose the enzyme was partially purified by a combination of affinity chromatography and fast liquid protein chromatography.

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on Hereditary Fructose Intolerance (HFI), or aldolase B deficiency, and fructose malabsorption (intestinal fructose intolerance)

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Hereditary Fructose Intolerance (HFI), also known as aldolase B deficiency, is an inherited metabolic disorder caused by the deficiency of that enzyme, which participates in the fructose metabolism in the liver, kidneys and small intestine. Aldolase B deficiency brings about the accumulation of fructose‐1‐phosphate in these organs, which can ...

Systematic Metabolic Engineering and Model‐Guided Optimization for High‐Level Production of L‐Theanine from Xylose in Escherichia coli

Advanced Science, Volume 13, Issue 17, 23 March 2026.
This study is pioneering in constructing the shortest known synthetic pathway for L‐theanine production from xylose within E coli. Through comprehensive metabolic engineering strategies, our engineered strain achieved the highest reported L‐theanine titer from xylose, with a titer of 95.42 g/L, and a yield of 0.55 g/g.

Cloning and Expression of a Xylitol-4-Dehydrogenase Gene from Pantoea ananatis [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT The Pantoea ananatis ATCC 43072 mutant strain is capable of growing with xylitol as the sole carbon source. The xylitol-4-dehydrogenase (XDH) catalyzing the oxidation of xylitol to l -xylulose was isolated from the cell extract of this strain.

Seasonal and Environmental Influences on Free Sugar and Amino Acid Profiles of Lycium barbarum Berries Cultivated in Southern Tuscany

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
The graphical abstract illustrates how temperature, rainfall, and ripening stage shape the metabolic profile of Lycium barbarum berries grown in Southern Tuscany. It highlights the optimal harvest window (S2–S4) and summarizes key trends in sugars (glucose, fructose, pectins) and amino acids (total FAAs, proline, BABA, ornithine). Visual cues show that

Xylose reductase from Pichia stipitis with altered coenzyme preference improves ethanolic xylose fermentation by recombinant Saccharomyces cerevisiae

Biotechnology for Biofuels, 2009
Background Xylose reductase (XR) and xylitol dehydrogenase (XDH) from Pichia stipitis are the two enzymes most commonly used in recombinant Saccharomyces cerevisiae strains engineered for xylose utilization.

Tailored GelMA‐Chitosan‐Polypyrrole‐ CNT Conductive Scaffold for Potential Application in Neural Tissue Regeneration

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
This study presents an optimal hydrogel that matches the physicochemical and biological properties of neural tissue. The presence of carbon nanotubes and polypyrrole in the GelMA‐chitosan matrix improved the biomechanical and bioelectric properties of the scaffold and increased the adhesion and viability of PC12 and SH‐SY5Y cells.

Comparative xylose metabolism among the Ascomycetes C. albicans, S. stipitis and S. cerevisiae.

PLoS ONE, 2013
The ascomycetes Candida albicans, Saccharomyces cerevisiae and Scheffersomyces stipitis metabolize the pentose sugar xylose very differently. S. cerevisiae fails to grow on xylose, while C. albicans can grow, and S.

Altering the coenzyme preference of xylose reductase to favor utilization of NADH enhances ethanol yield from xylose in a metabolically engineered strain of Saccharomyces cerevisiae

Microbial Cell Factories, 2008
Background Metabolic engineering of Saccharomyces cerevisiae for xylose fermentation into fuel ethanol has oftentimes relied on insertion of a heterologous pathway that consists of xylose reductase (XR) and xylitol dehydrogenase (XDH) and brings about ...
