Xylose Isomerase (XI) is an intramolecular oxidoreductase enzyme and catalyzes the reversible conversion of ketoses and aldoses in addition to the bioconversion of ethanol from xylose in the production of bioethanol from hemicellulose.

Engineering xylose metabolism in thraustochytrid T18
Background Thraustochytrids are heterotrophic, oleaginous, marine protists with a significant potential for biofuel production. High-value co-products can off-set production costs; however, the cost of raw materials, and in particular carbon, is a major ...

The production of poly-γ-glutamic acid (γ-PGA), a biopolymer consisting of D- and L-glutamic acid monomers, currently relies on L-glutamate, or citrate as carbon substrates. Here we aimed at using plant biomass-derived substrates such as xylose.

D-Xylose fermentation to ethanol bySchizosaccharomyces pombe cloned with xylose isomerase gene [PDF]
Schizosaccharomycespombe cloned with the xylose isomerase gene from E. coli is able to grow on YNB and YMP broths containing xylose as the sole carbon source. This yeast can ferment D-xylose to ethanol directly; however, the ethanol production rate and the yield were dependent on the nitrogen source.

Crystallographic Studies of d-Xylose Isomerase
In order to emphasize the similarity of the unit cell and of the diffraction patterns, this convention is only followed for Form B. The estimated error in unit cell measurements is 0.05 A for Form A crystals and 0.15 A for Form B crystals. The determined densities were reproducible within 0.02 g per cc.

Anomeric specificity of D-xylose isomerase
Crystal structures of complexes of D-xylose isomerase with deoxysugars have been determined. Deoxynojirimycin is a structural analogue of alpha-pyranose and mimics the binding of these aldose substrates. The structure of this complex supports the hypothesis that an imidazole group catalyzes ring opening of the pyranose.
