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-glycosyltransferase is an enzyme in prokaryotes which transfers individual hexoses onto asparagine sidechains in substrate proteins, using a nucleotide-bound intermediary, within the cytoplasm. They are distinct from regular N -glycosylating enzymes , which are oligosaccharyltransferases that transfer pre-assembled oligosaccharides .
Beta-glucosyltransferase is an enzyme, or more specifically an inverting glycosyltransferase (GT). In other words, it transfers glucose from uridine diphospho-glucose (UDPglucose) to an acceptor, modified DNA through beta-Glycosidic bond. The role of the enzyme is to protect the infecting viral DNA from the bacteria's restriction enzymes ...
They are bacterial enzymes belonging to the same family of the α-amylase specifically known as glycosyl-hydrolase family 13. This peculiar enzyme is capable of catalyzing more than one reaction with the most important being the synthesis of non-reducing cyclic dextrins known as cyclodextrins starting from starch, amylose, and other ...
Maltodextrin phosphorylase is a phosphorylase enzyme , more specifically one type of glycosyltransferase . Maltodextrin phosphorylase plays a critical role in maltodextrin metabolism in E. coli . This bacterial enzyme, often referred to as MalP, catalyzes the phosphorolysis of an α-1,4-glycosidic bond in maltodextrins, removing the non ...
These enzymes catalyse the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. A classification of glycosyltransferases using nucleotide diphospho-sugar, nucleotide monophospho-sugar and sugar phosphates ( EC 2.4.1.- ) and related proteins into distinct sequence based families has ...
Glycogen debranching enzyme is the only known eukaryotic enzyme that contains multiple catalytic sites and is active as a monomer. [ 21 ] [ 22 ] Some studies have shown that the C-terminal half of yeast GDE is associated with glucosidase activity, while the N-terminal half is associated with glucosyltransferase activity. [ 19 ]
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.
