Overview of Catalytic Properties of Fungal Xylose Reductases and Molecular Engineering Approaches for Improved Xylose Utilisation in Yeast

Applied Food Biotechnology, 2018
Background and Objective: Xylose reductases belong to the aldo-keto reductase family of enzymes, which catalyse the conversion of xylose to xylitol. Yeast xylose reductases have been intensively studied in the last two decades due to their significance ...

Antisense inhibition of xylitol dehydrogenase gene, xdh1 from Trichoderma reesei [PDF]

Letters in Applied Microbiology, 2005
To inhibit xylitol dehydrogenase (XDH) in Trichoderma reesei by antisense inhibition strategy and construct novel strains capable of accumulating xylitol.The xdh1 antisense expression plasmid pGTA-xdh was constructed by inserting xdh1 DNA fragment inversely between the gpdA promoter and the trpC terminator from Aspergillus nidulans into a pUC19 plasmid

Construction of a CO2‐Fixing Compartment Using a Shape‐Transforming DNA Scaffold

Chemistry – A European Journal, Volume 32, Issue 19, 22 May 2026.
A shape‐transforming DNA scaffold encapsulates RuBisCO within a controllable, self‐contacting compartment that mimics the carboxysome. The scaffold switches between open and closed states, enabling direct comparison of identical enzyme populations in different microenvironments.

Dual relationships of xylitol and alcohol dehydrogenases in families of two protein types [PDF]

FEBS Letters, 1993
Xylitol dehydrogenase encoded by gene XYL2 from Pichia stipitis is a member of the medium‐chain alcohol dehydrogenase family, as evidenced by the domain organization and a distant homology (24% residue identity with the human class Iγ1 alcohol dehydrogenase).

Ethanol and Xylitol Co-Production by Clavispora lusitaniae Growing on Saccharified Sugar Cane Bagasse in Anaerobic/Microaerobic Conditions

Fermentation
Ethanol and xylitol are valuable bioproducts synthesized by non-conventional yeasts from lignocellulosic sugars. However, their biosynthesis requires distinct cultivation conditions.

Production of bio-xylitol from d-xylose by an engineered Pichia pastoris expressing a recombinant xylose reductase did not require any auxiliary substrate as electron donor

Microbial Cell Factories, 2021
Background Xylitol is a five-carbon sugar alcohol that has numerous beneficial health properties. It has almost the same sweetness as sucrose but has lower energy value compared to the sucrose.
