| Sysname |
UDP-N-acetyl-D-glucosamine:beta-D-mannosyl-glycoprotein
4-beta-N-acetyl-D-glucosaminyltransferase |
| Reaction(IUBMB) |
UDP-N-acetyl-D-glucosamine + beta-D-mannosyl-R = UDP +
4-(N-acetyl-beta-D-glucosaminyl)-beta-D-mannosyl-R [RN:R07259] |
| Reaction(KEGG) |
R07259;
(other) R05986(G)
 |
| Substrate |
UDP-N-acetyl-D-glucosamine [CPD:C00043];
beta-D-mannosyl-R [CPD:C04942] |
| Product |
UDP [CPD:C00015];
4-(N-acetyl-beta-D-glucosaminyl)-beta-D-mannosyl-R [CPD:C15544] |
| Comment |
R represents the remainder of the N-linked oligosaccharide in the
glycoprotein acceptor (click here for diagram). The action of this
enzyme probably prevents further attachment of N-acetylglucosamine
residues to the growing carbohydrate chain. |
