3D Structure StatusGT-A
NoteDistant similarity to family GT24; The animal LARGE bifunctional glycosyltransferases are made of two domains. The N-terminal domain, which adds a-1,3-Xyl residues, belongs to family GT8 while the C-terminal domain, which adds b-1,3-GlcA residues, belongs to family GT49.
