A-1,3-manozil-glikoprotein 2-b-N-acetilglukozaminiltransferaza (EC 2.4.1.101, N-acetilglukozaminiltransferaza I, N-glikozil-oligosaharid-glikoprotein N-acetilglukozaminiltransferaza I, uridin difosfoacetilglukozamin-alfa-1,3-manozilglikoprotein beta-1,2-N-acetilglukozaminiltransferaza, UDP-N-acetilglukozaminil:alfa-1,3-D-manozid-beta-1,2-N-acetilglukozaminiltransferaza I, UDP-N-acetilglukozaminil:alfa-3-D-manozid beta-1,2-N-acetilglukozaminiltransferaza I, alfa-1,3-manozil-glikoprotein beta-1,2-N-acetilglukozaminiltransferaza, GnTI) je enzim sa sistematskim imenom UDP-N-acetil-D-glukozamin:3-(alfa-D-manozil)-beta-D-manozil-glikoprotein 2-beta-N-acetil-D-glukozaminiltransferaza.[1][2][3][4][5][6][7][8] Ovaj enzim katalizuje sledeću hemijsku reakciju
- UDP-N-acetil-D-glukozamin + 3-(alfa-D-manozil)-beta-D-manozil-R UDP + 3-(2-[N-acetil-beta-D-glukozaminil]-alfa-D-manozil)-beta-D-manozil-R
R predstavlja ostatak N-vezanog oligosaharida u glikoproteinskom akceptoru.
