N-acetil-beta-glukozaminil-glikoprotein 4-beta-N-acetilgalaktozaminiltransferaza (EC 2.4.1.244, beta1,4-N-acetilgalaktozaminiltransferaza III, beta4GalNAc-T3, beta1,4-N-acetilgalaktozaminiltransferaza IV, beta4GalNAc-T4, UDP-N-acetil-D-galaktozamin:N-acetil-D-glukozaminil-grupa beta-1,4-N-acetilgalaktozaminiltransferaza) je enzim sa sistematskim imenom UDP-N-acetil-D-galaktozamin:N-acetil-beta-D-glukozaminil-grupa 4-beta-N-acetilgalaktozaminiltransferaza.[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju
- UDP-N-acetil-D-galaktozamin + N-acetil-beta-D-glukozaminilna grupa UDP + N-acetil-beta-D-galaktozaminil-(1->4)-N-acetil-beta-D-glukozaminilna grupa
Ljudski enzim može da prenese N-acetil-D-galaktozamin (GalNAc) na N-glikanski i O-glikanski supstrat koji ima N-acetil-D-glukozamin (GlcNAc).
