Most glycosyltransferase enzymes form one of two folds: GT-A or GT-B. Glycosyltransferases (GTFs, Gtfs) are enzymes that establish natural glycosidic linkages.They catalyze the transfer of saccharide moieties from an activated nucleotide sugar (also known as the "glycosyl donor") to a nucleophilic glycosyl acceptor molecule, the nucleophile of which can be oxygen- carbon-, nitrogen-, or sulfur ...
N-glycosyltransferases are an unusual [a] type of glycosyltransferase which joins single hexoses to the target protein. [6] [7] [4] Attachment of sugars to the nitrogen atom in an amide group — such as the amide group of an asparagine — requires an enzyme, as the electrons of the nitrogen are delocalized in a pi-electron system with the carbon of the amide.
Glucosyltransferases are a type of glycosyltransferase that enable the transfer of glucose. [1] Examples include: glycogen synthase; glycogen phosphorylase; They are categorized under EC number 2.4.1.
This enzyme belongs to the family of transferases, specifically those glycosyltransferases hexosyltransferases. The systematic name of this enzyme class is UDP-N-acetyl-D-galactosamine:glycoprotein-alpha-L-fucosyl-(1,2)-D-ga lactose 3-N-acetyl-D-galactosaminyltransferase .
Mutations that change the amino acid sequence of the exostosin glycosyltransferase-2 protein can lead to it becoming unfunctional. When this protein is unfunctional it causes the heparan sulfate chains to become shorter. The chains are still formed and extended by the other proteins encoded by the EXT family genes, although not to the same extent.
RPN2 is a unique integral glycoprotein in rough ER membrane that is involved in translocation and the maintenance of the structural uniqueness of the rough ER. It is also an essential subunit of N-oligosaccharyl transferase complex that conjugates high mannose oligosaccharides to asparagine residues in the N-X-S/T consensus motif of nascent polypeptide chains.
Galactosyltransferase is a type of glycosyltransferase which catalyzes the transfer of galactose. An example is B-N-acetylglucosaminyl-glycopeptide b-1,4-galactosyltransferase . The biosynthesis of disaccharides, oligosaccharides and polysaccharides involves the action of hundreds of different glycosyltransferases.
