Globotriaosylceramide 3-beta-N-acetylgalactosaminyltransferase

In enzymology, a globotriaosylceramide 3-beta-N-acetylgalactosaminyltransferase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are UDP-N-acetyl-D-galactosamine, alpha-D-galactosyl--beta-D-galactosyl--beta-D-glucosyl-, and -ceramide, whereas its 3 products are UDP, N-acetyl-beta-D-galactosaminyl--alpha-D-galactosyl--, and beta-D-galactosyl--beta-D-glucosyl--ceramide.
Wrongly characterized previously as globotriosylceramide beta-1,6-N-acetylgalactosaminyl-transferase -beta-D-galact osyl--beta-D-glucosyl--ceramide III3-beta-N-acetyl-D-galactosaminyltransferase'''. This enzyme participates in glycosphingolipid biosynthesis - globoseries and glycan structures - biosynthesis 2.
