Engineering the xylose metabolism in Schizochytrium sp. to improve the utilization of lignocellulose

open access: yesBiotechnology for Biofuels and Bioproducts, 2022
Background Schizochytrium sp. is a heterotrophic, oil-producing microorganism that can efficiently produce lipids. However, the industrial production of bulk chemicals using Schizochytrium sp.

Different transcriptional responses of haploid and diploid S. cerevisiae strains to changes in cofactor preference of XR

open access: yesMicrobial Cell Factories, 2020
Background Xylitol accumulation is a major barrier for efficient ethanol production through heterologous xylose reductase-xylitol dehydrogenase (XR-XDH) pathway in recombinant Saccharomyces cerevisiae.

Metabolic engineering of Saccharomyces cerevisiae for second-generation ethanol production from xylo-oligosaccharides and acetate

open access: yesScientific Reports, 2023
Simultaneous intracellular depolymerization of xylo-oligosaccharides (XOS) and acetate fermentation by engineered Saccharomyces cerevisiae offers significant potential for more cost-effective second-generation (2G) ethanol production. In the present work,

A single amino acid change (Y318F) in the L-arabitol dehydrogenase (LadA) from Aspergillus niger results in a significant increase in affinity for D-sorbitol

open access: yesBMC Microbiology, 2009
Background L-arabitol dehydrogenase (LAD) and xylitol dehydrogenase (XDH) are involved in the degradation of L-arabinose and D-xylose, which are among the most abundant monosaccharides on earth. Previous data demonstrated that LAD and XDH not only differ

Influence of L-lactate and low glucose concentrations on the metabolism and the toxin formation of Clostridioides difficile.

open access: yesPLoS ONE, 2021
The virulence of Clostridioides difficile (formerly Clostridium difficile) is mainly caused by its two toxins A and B. Their formation is significantly regulated by metabolic processes.

Evidence that the gene YLR070c of Saccharomyces cerevisiae encodes a xylitol dehydrogenase [PDF]

open access: yesFEBS Letters, 1999
The open reading frame YLR070c of Saccharomyces cerevisiae has high sequence similarity to S. cerevisiae sorbitol dehydrogenase and to xylitol dehydrogenase of Pichia stipitis. Overexpression of this open reading frame in S. cerevisiae resulted in xylitol dehydrogenase activity. The enzyme is specific for NADH.

Genetic analysis of D-xylose metabolism by endophytic yeast strains of Rhodotorula graminis and Rhodotorula mucilaginosa

open access: yesGenetics and Molecular Biology, 2011
Two novel endophytic yeast strains, WP1 and PTD3, isolated from within the stems of poplar (Populus) trees, were genetically characterized with respect to their xylose metabolism genes. These two strains, belonging to the species Rhodotorula graminis and

The potential use of xylitol in glucose-6-phosphate dehydrogenase deficiency anemia [PDF]

open access: yesJournal of Clinical Investigation, 1971
NADP-linked xylitol dehydrogenase has been found to be present in human red blood cells. This enzyme activity is normal in most glucose-6-phosphate dehydrogenase (G6PD)-deficient red cells. Xylitol was explored as a potential agent for treatment of hemolysis in patients with G6PD-deficiency.

Cloning of the Xylitol Dehydrogenase Gene fromGluconobacter oxydansand Improved Production of Xylitol fromD-Arabitol

open access: yesBioscience, Biotechnology, and Biochemistry, 2003
Xylitol dehydrogenase (XDH) was purified from the cytoplasmic fraction of Gluconobacter oxydans ATCC 621. The purified enzyme reduced D-xylulose to xylitol in the presence of NADH with an optimum pH of around 5.0. Based on the determined NH2-terminal amino acid sequence, the gene encoding xdh was cloned, and its identity was confirmed by expression in ...
