Publication number: 20160272953Abstract: Kinase and nucleotidyltransferase enzymes for the production of activated sugars have been developed. These enzymes have improved stability for industrial application and relaxed specificity towards a variety of sugars. These enzymes are useful in, for example, the production of diverse NDP-sugars for glycosylation of aglycones of interest, production of oligosaccharides, production of other important glycoylated sugars, and in drug discovery applications.Type: ApplicationFiled: June 3, 2016Publication date: September 22, 2016Inventors: Ryan Woodyer, Paul Taylor, David Demirjian

Publication number: 20090325254Abstract: A new xylose reductase encoding gene from Neurspora crassa was heterologously expressed in E. coli as a His-tag fusion protein and subsequently purified in high yield. This xylose reductase was shown to have a high turnover rate and catalytic efficiency, high stability at room temperature, broad pH profile, and a preference of NADPH over NADH. This enzyme is utilized in production of xylitol and other sugar alcohols such as sorbitol and also in the metabolic enhancement of organisms used for fermentation of plant biomass into ethanol.Type: ApplicationFiled: September 1, 2009Publication date: December 31, 2009Applicants: BIOTECHNOLOGY RESEARCH AND DEVELOPMENT CORPORATION, THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOISInventors: Huimin Zhao, Ryan Woodyer, Michael Simurdiak, Wilfred A. van der Donk
