Phosphate sugar isomerases and their potential for rare sugar bioconversion
Journal of Microbiology, 2020Phosphate sugar isomerases, catalyzing the isomerization between ketopentose/ketohexose phosphate and aldopentose/aldohexose phosphate, play an important role in microbial sugar metabolism. They are present in a wide range of microorganisms. They have attracted increasing research interest because of their broad substrate specificity and great ...

Enzymatic approaches to rare sugar production
Biotechnology Advances, 2017Rare sugars have recently attracted much attention because of their potential applications in the food, nutraceutical, and pharmaceutical industries. A systematic strategy for enzymatic production of rare sugars, named Izumoring, was developed >10years ago.

Rare sugars and sugar-based synthons by chemo-enzymatic synthesis
Enzyme and Microbial Technology, 2000The unique catalytic potential of the fungal enzyme pyranose oxidase was demonstrated by preparative conversions of a variety of carbohydrates, and by extensive chemical characterization of the reaction products with NMR spectroscopy. The studies revealed that POx not only oxidizes most substrates very efficiently but also that POx possesses a glycosyl-

Fluorine-directed 1,2-trans glycosylation of rare sugars
Organic & Biomolecular Chemistry, 2016To reconcile the urgent need to access well defined β-configured 2,6-di-deoxypyranose analogues for chemical biology, with the intrinsic α-selectivity of the native system, the directing role of fluorine at C2 has been explored.

Bioproduction strategies for rare hexose sugars
Naturwissenschaften, 2002A new strategy for the bioproduction of all ketohexoses was developed using hexitols as intermediates. Biocatalysts used to employ the strategy were D-tagatose 3-epimerase, which epimerizes ketohexoses at the C-3 position, and oxidoreductases, which catalyze oxidation-reduction reactions between ketohexoses and the corresponding hexitols. Arranging all

Synthesis of rare sugar isomers through site-selective epimerization
Nature, 2020Glycans have diverse physiological functions, ranging from energy storage and structural integrity to cell signalling and the regulation of intracellular processes1. Although biomass-derived carbohydrates (such as D-glucose, D-xylose and D-galactose) are extracted on commercial scales, and serve as renewable chemical feedstocks and building blocks2,3 ...

Angewandte Chemie International Edition in English, 1969
AbstractThe use of new oxidation reagents, such as the Pfitzner‐Moffatt reagent, dimethyl sulfoxide‐acid anhydrides, and ruthenium tetroxide, has significantly improved the yields obtained on oxidation of a secondary hydroxyl group to a carbonyl group in suitably protected sugars.
