The interaction of alpha-D-glucopyranosyl pyrophosphates of 5-X-uridines (X = CH3, NH2, CH3O, I, Br, Cl, OH) with uridine diphosphate glucose (UDPGlc) dehydrogenase (EC 1.1.1.22) from calf liver has been studied. All the derivatives investigated were able to serve as substrates for the enzyme.

Uridine diphosphate glucose dehydrogenase of calf liver
Biochemical Pharmacology, 1971Abstract UDP-glucose dehydrogenase of calf liver dissociated in guanidine-HCl into six subunits. The number of reactive sulfhydrylgroups of native and guanidine-HCl-treated enzyme was found to be 20 ± 1 and 46 ± 1, respectively, per mole of native enzyme.

Publisher Summary This chapter describes the isolation of uridine diphosphate glucose, uridine diphosphate acetylglucosamine, and guanosine diphosphate mannose. The basic principle is that alcoholic extract from toluene-autolyzed yeast is fractionated on anion-exchange columns.

Blood Uridine Diphosphate Glucose in Mental Disease
British Journal of Psychiatry, 1969Neither older (Raiman, 1902; Ehrenberg, 1909; Wigert, 1918; Reiter, 1925) nor more recent papers (Diethelm, 1936; McFarland and Goldstein, 1939; Holmgren and Wohlfarhrt, 1944) provide general agreement about impairment of glucose tolerance in mental disease.

Interaction of uridine diphosphate glucose with calf liver uridine diphosphate glucose dehydrogenase
Biochimica et Biophysica Acta (BBA) - Enzymology, 1975Analogs of uridine diphosphate glucose (UDPGlc) with a modified hexosyl residue which contained a deoxy-unit at C-3 or C-4 were tested as substrates of calf liver UDPGlc dehydrogenase (EC 1.1.1.22). The 3-deoxyglucose derivative was found not to serve as a substrate for the enzyme whereas the 4-deoxyglucose analog was able to participate in the ...

Analogues of uridine 5′‐diphosphate glucose and guanosine 5′‐diphosphate mannose
Recueil des Travaux Chimiques des Pays-Bas, 1990AbstractOne‐pot coupling of 2′,3′‐di‐O‐benzoyl‐uridine and 4,5,6,8‐tetra‐O‐acetyl‐3,7‐anhydro‐2‐deoxy‐D‐glycero‐D‐ido‐octitol with appropriate bifunctional phosphoro‐, phosphono‐ and thiophosphonylation reagents gave, after removal of the base‐labile protecting groups, analogues of UDP‐Glc containing charged phosphate, neutral alkyl‐ and ...

The present study investigates the biotransformation of glucose with uridine monophosphate (UMP) to obtain sugar nucleotide, UDP-glucose (UDPG), by the dried cells of Candida saitoana KCTC7249. The biotransformation was optimized by varying the concentrations of substrates and phosphate ion.

Uridine diphosphate glucose and the synthesis of phenolic glucosides by mollusks
Archives of Biochemistry and Biophysics, 1966Abstract Formation of the glucoside of o-aminophenol and probably also of those of p-nitrophenol and phenolphthalein has been demonstrated in the mollusks Arion ater and Helix pomatia. The mechanism is glucosyl transference from UDP-glucose and not from simple glucosides.

1. The rate of acid hydrolysis of uridine diphosphate glucose as functions of the pH and the temperature is expressed by the equation $$\log {\text{k}}(\min ^{ - 1} ) = 25.45 - {\text{pH}} - \frac{{8300}}{{\text{T}}}.$$ 2. The expression for the rate constant as functions of the pH and the temperature that has been obtained is in ...
