  • Patent number: 6569649
    Abstract: Processes for preparing oligosaccharides, polysaccharides, glycolipids, glycoproteins, and other saccharide compositions are provided which involve the enzyme facilitated transfer of a preselected saccharide unit from a donor moiety to an acceptor moiety. In accordance with a preferred embodiment, saccharide compositions having a plurality of saccharide units are prepared by appending the saccharide units in iterative fashion to acceptor moieties which are themselves saccharide compositions prepared in accordance with this invention.

    Inventor: Stephen Roth
  • Patent number: 6544778
    Abstract: A method for preparing saccharide compositions is disclosed. The method is reiterative and comprises the following three steps. (i) A glycosyltransferase capable of transferring a preselected saccharide unit to an acceptor moiety is isolated by contacting the acceptor moiety with a mixture suspected of containing the glycosyltransferase under conditions effective to bind the acceptor moiety and the glycosyltransferase and thereby isolate the glycosyltransferase. The acceptor moiety is a protein, a glycoprotein, a lipid, a glycolipid, or a carbohydrate. (ii) The isolated glycosyltransferase is then used to catalyze the bond between the acceptor moiety and the preselected saccharide unit. (iii) Steps (i) and (ii) are repeated a plurality of times with the intermediate product obtained in the first iteration of the method being used as the acceptor moiety of the second iteration.
