LITERATURE
synthesis
engineering of Escherichia coli to divert the flow of carbon flux from glucose-1-phosphate to thymidine diphosphate 4-keto 4,6-dideoxy-D-glucose (dTKDG), an intermediate of various dTDP-sugars. Glucose phosphate isomerase, glucose-6-phosphate dehydrogenase and uridylyltransferase genes are deleted while dTDP-D-glucose synthase and dTDP-Dglucose 4,6-dehydratase are overexpressed to produce a pool of dTKDG in the cell cytosol. The flow of dTKDG is further diverted to dTDP-D-viosamine, dTDP 4-amino 4,6-dideoxy-D-galactose, and dTDP 3-amino 3,6-dideoxy-D-galactose sugars using sugar aminotransferases gerB, wecE, and fdtB, respectively, from different sources. These sugar moieties are transferred to the 3-hydroxyl position of quercetin and kaempferol with the help of Arabidopsis thaliana glycosyltransferase ArGT3
