Hydroxylysine (Hyl) is an amino acid with the molecular formula C6H14N2O3. It was first discovered in 1921 by Donald Van Slyke as the 5-hydroxylysine form. It arises from a post-translational hydroxy modification of lysine. It is most widely known as a component of collagen.
Glycosyltransferases are enzymes that establish natural glycosidic linkages. They catalyze the transfer of saccharide moieties from an activated nucleotide sugar to a nucleophilic glycosyl acceptor molecule, the nucleophile of which can be oxygen- carbon-, nitrogen-, or sulfur-based.
Galactosyltransferase is a type of glycosyltransferase which catalyzes the transfer of galactose. An example is B-N-acetylglucosaminyl-glycopeptide b-1,4-galactosyltransferase.
N-acetyllactosamine synthase is a galactosyltransferase enzyme. It is a component of lactose synthase This enzyme modifies the connection between two molecule UDP-galactose and N-actyl-D-glucosamine and generates two different molecules UDP and N-acetyllactosamine as products. The main function of the enzyme is associated with the biosynthesis of glycoproteins and glycolipids in both human and animals. In human, the activity of this enzyme can be found in Golgi apparatus.
