Comparison of the xylose reductase-xylitol dehydrogenase and the xylose isomerase pathways for xylose fermentation by recombinant Saccharomyces cerevisiae

Microbial Cell Factories, 2007
Background Two heterologous pathways have been used to construct recombinant xylose-fermenting Saccharomyces cerevisiae strains: i) the xylose reductase (XR) and xylitol dehydrogenase (XDH) pathway and ii) the xylose isomerase (XI) pathway.

Purification and characterization of xylitol dehydrogenase from Fusarium oxysporum

, 2002
An NAD(+)-dependent xylitol dehydrogenase (XDH) from Fusarium oxysporum, a key enzyme in the conversion of xylose to ethanol, was purified to homogeneity and characterised. It was homodimeric with a subunit of M-r 48 000, and pI 3.6.

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 ...

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.

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.
