• 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.

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.
