(57) ABSTRACT

This invention relates to methods and compositions for the in vitro production of glycoconjugates. In particular, a preferred production system is provided that comprises a solid support, at least one sugar nucleotide producing enZyme; at least one glycosyltransferase; at least one bioen

ergetic; and at least one acceptor. The sugar nucleotide producing enZyme(s) is preferably immobilized on the solid support. The glycosyltransferase may be co-immobiliZed on the solid support With the sugar nucleotide producing enZyme(s), or may be provided to the solid support in solution.
