General description

Uridine diphosphate glucose (UDP-glucose) is a glycogen precursor. The transfer of glucose from UDP-glucose to growing glycogen chain is catalyzed by the enzyme glycogen synthase. The enzyme uridine diphosphate galactose-4-epimerase catalyzes the formation of UDP-glucose from UDP-galactose.

Application

Uridine 5′-diphosphoglucose disodium salt hydrate from Saccharomyces cerevisiae has been used as a substrate
  • for the PpIRX10 enzyme activity from Arabidopsis thaliana
  • in radiometric assay of glycosyltransferases (GTs)
  • in uridine diphosphate glucose (UDP-Glc) 4-epimerase assay in Arabidopsis thaliana samples

Biochem/physiol Actions

Uridine diphosphate glucose (UDP-glucose) is an essential mediator of the cellular metabolic pathways. In yeast, the high levels of trehalose and glycogen favor increased levels of UDP-glucose.

Glycosyltransferases: Tools for Synthesis and Modification of Glycans

The presence of multiple functional groups and stereocenters in complex carbohydrates makes them challenging targets for the organic chemist.

Glycosyltransferases

Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some nucleoside mono- or diphosphate sugar donors.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
