Enzyme Information
| 2.4.1.101 |
Alpha-1,3-mannosyl-glycoprotein 2-beta-N-acetylglucosaminyltransferase.
based on mapping to UniProt P27115
UDP-N-acetyl-D-glucosamine + 3-(alpha-D-mannosyl)-beta-D-mannosyl-R = UDP + 3-(2-(N-acetyl-beta-D-glucosaminyl)-alpha-D-mannosyl)-beta-D- mannosyl-R.
-!- R represents the remainder of the N-linked oligosaccharide in the glycoprotein acceptor. -!- Note that this enzyme acts before N-acetylglucosaminyltransferases II (EC 2.4.1.143), III (EC 2.4.1.144), IV (EC 2.4.1.145), V (EC 2.4.1.155) and VI (EC 2.4.1.201). -!- Formerly EC 2.4.1.51.
