GlycosylTransferase Family 64

Activities in FamilyUDP-GlcNAc: heparan α-N-acetylhexosaminyltransferase (EC 2.4.1.224)
Mechanism Retaining
3D Structure StatusGT-A
NoteThe long animal heparan synthases are made of two domains. The N-terminal domain, which adds b-1,4-GlcA residues, belongs to family GT47 while the C-terminal domain, which adds a-1,4-GlcNAc residues, belongs to family GT64. The plant homologs have a single domain.
