Description

A alpha-N-acetylgalactosaminyltransferase is an enzyme that catalyzes the chemical reaction: UDP-N-acetyl-D-galactosamine + glycoprotein-alpha-L-fucosyl-(1,2)-D-galactose → UDP + glycoprotein-N-acetyl-alpha-D-galactosaminyl-(1,3)-[alpha-L-fucosyl-(1,2)]-D-galactose.

Unit Definition

One unit is defined as the amount of enzyme that catalyzes the formation of 1 μmol GalNAc1,3(Fuc1,2)Gal from Fuc1,2Gal per minute at 37 °C.
