GT3 enzymes are characterized by their ability to catalyze the transfer of glycosyl groups from nucleoside diphosphate sugars to a variety of acceptors, including proteins, lipids, and small molecules. The family is defined based on sequence homology and shared structural features. These enzymes are involved in the formation of glycosidic bonds, which are pivotal in the construction of complex carbohydrates and glycoconjugates.
