Abstract

A method for preparing saccharide compositions is disclosed. The method is reiterative and includes 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.
