| 3D Structure Status | GT-B |
| Note | The 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, which have a single domain, display various specificities ranging from xyloglucan b-galactosyltransferase to a pectin b-glucuronyltransferase and arabinan a-L-arabinosyltransferase. |
