General annotation (Comments)

Function

Responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids. Can produce lactose By similarity.

Catalytic activity

UDP-alpha-D-galactose + D-glucose = UDP + lactose.

UDP-alpha-D-galactose + N-acetyl-beta-D-glucosaminylglycopeptide = UDP + beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminylglycopeptide.

UDP-alpha-D-galactose + N-acetyl-D-glucosamine = UDP + N-acetyllactosamine.

Cofactor

Manganese By similarity.

Pathway

Protein modification; protein glycosylation.

Subcellular location

Golgi apparatusGolgi stack membrane; Single-pass type II membrane protein By similarity. Note: Trans cisternae of Golgi stack By similarity.

Sequence similarities

Belongs to the glycosyltransferase 7 family.
