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 ...
The two steps of glycogen breakdown, glucosyltransferase and glucosidase, are performed by a single enzyme in mammals, yeast, and some bacteria, but by two distinct enzymes in E. coli and other bacteria, complicating nomenclature. Proteins that catalyze both functions are referred to as glycogen debranching enzymes (GDEs).
Uridine 5'-diphospho-glucuronosyltransferase (UDP-glucuronosyltransferase, UGT) is a microsomal glycosyltransferase (EC 2.4.1.17) that catalyzes the transfer of the glucuronic acid component of UDP-glucuronic acid to a small hydrophobic molecule. This is a glucuronidation reaction. [2] [3] Alternative names:
Glycosyltransferase is a subcategory of EC 2.4 transferases that is involved in biosynthesis of disaccharides and polysaccharides through transfer of monosaccharides to other molecules. [40] An example of a prominent glycosyltransferase is lactose synthase which is a dimer possessing two protein subunits.
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.
Thus, degrading the biofilm may increase antibiotic efficacy, and potentiate host immune function and healing ability. For example, a combination of alpha-amylase and cellulase was shown to degrade polymicrobial bacterial biofilms from both in vitro and in vivo sources, and increase antibiotic effectiveness against them.
