Cell-Free Multi-Enzyme Synthesis and Purification of Uridine Diphosphate Galactose. [PDF]
AbstractHigh costs and low availability of UDP‐galactose hampers the enzymatic synthesis of valuable oligosaccharides such as human milk oligosaccharides. Here, we report the development of a platform for the scalable, biocatalytic synthesis and purification of UDP‐galactose.

The enzymatic transformation of uridine diphosphate glucose into a galactose derivative [PDF]
Abstract Treatment of uridine diphosphate glucose (UDPG) with an enzyme of S. fragilis was found to produce about 25% of a galactose-containing compound. This compound is precipitated with mercuric ions like UDPG, and its migration in chromatography in acid-ethanol is similar.

Frog brain uridine diphosphate galactose–N-acetylgalactosaminyl-N-acetylneuraminylgalactosylglucosylceramide galactosyltransferase [PDF]
1. The enzyme that catalyses the transfer of galactose from UDP-galactose to N-acetylgalactosaminyl-(1→4)-N-acetylneuraminyl-(2→3)-galactosyl-(1→4)-glucosylceramide (GM2) was found mainly in the heavy- and light-microsomal fractions of the adult frog brain. 2.

Generalised uridine diphosphate galactose-4-epimerase deficiency [PDF]
The generalised form of epimerase deficiency galactosaemia has been described in only two children from unrelated families. Their progress is reported and three other affected children from these families are described. The initial presentation was similar to classic galactosaemia.

Developmental aspects of uridine diphosphate galactose 4-epimerase in rat intestine [PDF]
Kinetic and developmental characteristics of rat intestinal UDP-galactose 4-epimerase activity have been examined. The enzyme in the adult rat had a Vmax. value 2–3 times higher than that of the newborn animal, but the Km values for the enzyme in the newborn and adult rat were the same (0.17mm). No differences in epimerase activity were found along the

Lactogenesis in the rat. Metabolism of uridine diphosphate galactose by mammary gland [PDF]
1. Lactose synthetase activity in the rat mammary gland increases during the last day of pregnancy from an essentially zero value. There is a parallel increase of tissue lactose and of glucose 6-phosphate dehydrogenase activity. 2. Mammary-gland homogenates prepared both before and after parturition hydrolyse the lactose precursors glucose 6-phosphate,

Uridine Diphosphate-4-Keto-Glucose, an Intermediate in the Uridine Diphosphate-Galactose-4-Epimerase Reaction [PDF]
When UDP-galactose 4-epimerase (EC 5.1.3.2) from Escherichia coli is incubated with UDP-galactose, then reduced with NaB 3 H 4 , label is found in UDP-glucose and UDP-galactose.
