  名称：

  In vitro sulfation of N-acetyllactosaminide by soluble recombinant human β-Gal-3′-sulfotransferase

  摘要：

  Membrane-bound beta-Gal-3'-sulfotransferase (GP3ST) was expressed and used for in vitro sulfation of Tamm-Horsfall glycoprotein. Further, the regioselective transfer of sulfate to an N-acetyllactosamine derivative could be realised with soluble chimeric GMT, also in combination with Lac transglycosylation by means of beta-galactosidase. Two alternative straightforward chemical syntheses for the target compound could be elaborated. (c) 2006 Elsevier Ltd. All rights reserved.
