Activities in Family	lipopolysaccharide α-1,3-galactosyltransferase (EC 2.4.1.44); UDP-Glc: (glucosyl)lipopolysaccharide α-1,2-glucosyltransferase (EC 2.4.1.-); lipopolysaccharide glucosyltransferase 1 (EC 2.4.1.58); glycogenin glucosyltransferase (EC 2.4.1.186); inositol 1-α-galactosyltransferase (galactinol synthase) (EC 2.4.1.123); homogalacturonan α-1,4-galacturonosyltransferase (EC 2.4.1.43); UDP-GlcA: xylan α-glucuronyltransferase (EC 2.4.1.-); UDP-Gal:glucoside α-1,3-galactosyltransferase (EC 2.4.1.-)
Mechanism	Retaining
3D Structure Status	GT-A
Note	Distant similarity to family GT24; The animal LARGE bifunctional glycosyltransferases are made of two domains. The N-terminal domain, which adds a-1,3-Xyl residues, belongs to family GT8 while the C-terminal domain, which adds b-1,3-GlcA residues, belongs to family GT49.
