beta-1,4-Galactosyltransferase (LgtB)

Beta-1,4-Galactosyltransferase (LgtB) (B4GALT1(LgtB)), a key enzyme in biochemical research, catalyzes the transfer of UDP-galactose to N-acetylglucosamine, resulting in the synthesis of galactose beta-1,4-N-acetylglucosamine [1].

Alpha-1,4-Galactosyltransferase (LgtC) (A4GALT), a glycosphingolipid-specific glycosyltransferase, catalyzes the transfer of a galactose molecule to the alpha-1,4 position on lactosylceramide, resulting in the formation of globotriaosylceramide. This enzyme plays a crucial role in the synthesis of P1 blood group antigens [1] [2].

Beta-1,3-Galactosyltransferase (CgtB) (GM1-synthase), an enzyme critical for the production of sialylated lipooligosaccharide (LOS SIAL), plays a key role in biochemical research. This enzyme facilitates the incorporation of a galactose molecule essential for generating a GM1-like LOS SIAL structure.
