Impact of xylose epimerase on sugar assimilation and sensing in recombinant Saccharomyces cerevisiae carrying different xylose-utilization pathways

Biotechnology for Biofuels and Bioproducts, 2023
Background Over the last decades, many strategies to procure and improve xylose consumption in Saccharomyces cerevisiae have been reported. This includes the introduction of efficient xylose-assimilating enzymes, the improvement of xylose transport, or ...

DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

Small, Volume 22, Issue 43, 3 August 2026.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Expression of xylitol dehydrogenase gene xyl2 in Saccharomyces cerevisiae [PDF]

AIP Conference Proceedings, 2018
Xylitol is oxidized to xylulose under the catalytic action of xylitol dehydrogenase, so xylitol dehydrogenase is at an important position in the metabolism of wood pond. The paper discusses the extraction, structure, pear flower properties and coenzyme modification of xylitol dehydrogenase, and studies the cloning and expression of xylitol ...

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.

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.

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.

Oxygenation influences xylose fermentation and gene expression in the yeast genera Spathaspora and Scheffersomyces

Biotechnology for Biofuels and Bioproducts
Background Cost-effective production of biofuels from lignocellulose requires the fermentation of d-xylose. Many yeast species within and closely related to the genera Spathaspora and Scheffersomyces (both of the order Serinales) natively assimilate and ...
