General description

Uridine 5′-diphospho-α-D-galactose/UDP-Gal is a nucleotide sugar.

Application

Uridine 5′-diphosphogalactose disodium salt has been used as a component in galactosyltransferase labeling buffer to prelabel terminal N-acetylglucosamine (GlcNAc) on immunoglobulin chains. It has also been used as a component in Hyp O-galactosyltransferase (HPGT) assay.

Biochem/physiol Actions

Uridine 5′-diphospho-α-D-galactose/UDP-Gal can block BALB/3T12 cell development. In mammals, it is very essential for glycoconjugate biosynthesis.

The human UDP glycosyltransferase (UGT) superfamily comprises four families of enzymes that catalyze the addition of sugar residues to small lipophilic chemicals. The UGT1 and UGT2 enzymes use UDP-glucuronic acid, and UGT3 enzymes use UDP-N-acetylglucosamine, UDP-glucose, and UDP-xylose to conjugate

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.
