Accepted name: β-1,3-galactosyl-O-glycosyl-glycoprotein β-1,6-N-acetylglucosaminyltransferase
Reaction: UDP-N-acetyl-D-glucosamine + β-D-galactosyl-(1→3)-N-acetyl-D-galactosaminyl-R = UDP + β-D-galactosyl-(1→3)-[N-acetyl-β-D-glucosaminyl-(1→6)]-N-acetyl-D-galactosaminyl-R
Other name(s): O-glycosyl-oligosaccharide-glycoprotein N-acetylglucosaminyltransferase I; β6-N-acetylglucosaminyltransferase; uridine diphosphoacetylglucosamine-mucin β-(1→6)-acetylglucosaminyltransferase; core 2 acetylglucosaminyltransferase; core 6-β-GlcNAc-transferase A; UDP-N-acetyl-D-glucosamine:O-glycosyl-glycoprotein (N-acetyl-D-glucosamine to N-acetyl-D-galactosamine of β-D-galactosyl-1,3-N-acetyl-D-galactosaminyl-R) β-1,6-N-acetyl-D-glucosaminyltransferase
Systematic name: UDP-N-acetyl-D-glucosamine:O-glycosyl-glycoprotein (N-acetyl-D-glucosamine to N-acetyl-D-galactosamine of β-D-galactosyl-(1→3)-N-acetyl-D-galactosaminyl-R) 6-β-N-acetyl-D-glucosaminyltransferase
Comments: cf. EC 2.4.1.146 (β-1,3-galactosyl-O-glycosyl-glycoprotein β-1,3-N-acetylglucosaminyltransferase), EC 2.4.1.147 (acetylgalactosaminyl-O-glycosyl-glycoprotein β-1,3-N-acetylglucosaminyltransferase) and EC 2.4.1.148 (acetylgalactosaminyl-O-glycosyl-glycoprotein β-1,6-N-acetylglucosaminyltransferase).
