Structural Analysis of Xylose Isomerase from Streptomyces avermitilis

Crystals
Xylose isomerase (XI, also known as glucose isomerase) is an oxidoreductase that interconverts aldoses and ketoses. XI catalyzes the reversible isomerization of D-glucose and D-xylose into D-fructose and D-xylulose, respectively.

Exploring the xylose paradox in Saccharomyces cerevisiae through in vivo sugar signalomics of targeted deletants

Microbial Cell Factories, 2019
Background There have been many successful strategies to implement xylose metabolism in Saccharomyces cerevisiae, but no effort has so far enabled xylose utilization at rates comparable to that of glucose (the preferred sugar of this yeast). Many studies

Positive selection of efficient ethanol producers from xylose at 45 °C in the yeast Ogataea polymorpha

Scientific Reports
This research presents a method for the positive selection of mutants with improved xylose and L-arabinose fermentation in the thermotolerant, naturally xylose-utilizing yeast Ogataea polymorpha which is based on isolation of the mutants growing on L ...

Immobilization, Characterization and Application of a Xylose Isomerase Biocatalyst for Xylose Fermentation in Biorefineries

Fermentation
A biocatalyst has been developed for application in the simultaneous isomerization and fermentation (SIF) of xylose, which could enable operation in repeated batches and the use of xylose from biomass hemicellulose for the production of second-generation

Overexpression of Transketolase Relieves xylA Repression and Enhances Xylose Utilization in Saccharomyces cerevisiae During Mixed Sugar Fermentation

GCB Bioenergy
Metabolic engineering of Saccharomyces cerevisiae has enabled xylose‐fermenting yeast strains. However, the bioavailability dilemma of xylose has become the core bottleneck restricting the economy of lignocellulose.

Efficient calcium fumarate overproduction from xylose and corncob-derived xylose by engineered strains of Aureobasidium pullulans var. Aubasidani DH177

Microbial Cell Factories
Background Xylose from lignocellulose is one of the most abundant and important renewable and green raw materials. It is very important how to efficiently transform xylose into useful bioproducts such as fumaric acid and so on.
