The presence of uridine pyrophosphogalactose and uridine pyrophosphogalactose-4-epimerase in non-galactose adapted yeasts.
TLDR
The enzyme uridine pyrophosphoglucose-4-epimerase has been identified in non-galactose inadapted yeasts as well as in yeast grown on a galactose medium. Expand

TLDR
Uridine diphosphoglucose pyrophosphorylase from rat liver and guinea-pig brain is competitively inhibited by galactose i -phosphate, and inorganic orthophosphate is a non-competitive inhibitor. Expand
Exchange of 14C-Glucose-1-phosphate with Uridine-diphosphate-glucose by the Galacto-Waldenase System
A TWO-STEP reaction, as represented by reactions 1 and 2, has been proposed1 for the enzymatic transformation of galactoso-1-phosphate into glucose-1-phosphate:
Uridine diphosphoglycosyl compounds and theirimportance in metabolism
It is now about 10 years since the first isolation of a uridine nucleotide which was shown to have a definite role in intermediary metabolism.
Uridine Diphosphoglucose, Uridine Diphosphogalactose, Uridine Triphosphate and Uridine Diphosphoglucuronic Acid
Publisher Summary This chapter describes the enzymatic determination of uridine diphosphoglucose (UDPG), uridine diphosphogalactose (UDPGal), uridine triphosphate (UTP), and uridine… Expand
2 Uridine Diphosphoryl Glucose Pyrophosphorylase
Publisher Summary This chapter discusses uridine diphosphoryl glucose pyrophosphorylase (UTP:α-D-glucose-l-phosphate uridylyltransferase. EC 2.7.7.9). This enzyme catalyzes the formation of… Expand
Biotransformation of uridine monophosphate (UMP) and glucose to uridine diphosphate-glucose (UDPG) byCandida saitoana KCTC7249 cells
TLDR
The biotransformation of glucose with uridine monophosphate to obtain sugar nucleotide, UDP-glucose (UDPG), by the dried cells of Candida saitoana KCTC7249 indicates that the yeast-dried cells could be used for the production of nucleotide sugars for donor molecules of complex carbohydrate synthesis.

Uridine pyrophosphoglycosyl compounds and the formation of glucuronides by isolated enzyme systems.
TLDR
From these experiments, a mechanism of glucuronide formation from glucose and glycogen is proposed and discussed in relation to other work on the mechanism of cortisol formation. Expand
Uridine diphosphate glucose and the synthesis of phenolic glucosides by mollusks.

TLDR
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 and the role in vivo of molluskan UDP-glucosyltransferase is discussed. Expand
Uridine nucleotide compounds of liver.
TLDR
It has been shown that UDPAG and UDPG undergo a pyrophosphorolytic split to give UTP in the presence of isolated liver nuclei, and it is suggested that the structure of this compound may be different from that of UDPG andUDPAG. Expand
