The use of human polypeptide N-acetylgalactosaminytransferase T-4 (GalNAc-T4) to glycosylate substrates is disclosed. The action of GalNAc-T4 can complement the activities of GalNAc-T1, -T2 and -T3. The glycosylated substrates are useful in preparation of vaccines and anti-inflammatory agents. A method of producing the soluble form of the enzyme is also disclosed. |
