Oligosaccharide synthesis commercial products

Fig. 8. Different products with sucrose analogues as substrates.115 Enzymatic synthesis of 1-kestose, 1-nystose, and their analogues by /(-fructofuranosidase of A. niger. Structures of fructo-oligosaccharides (A) commercial products, (B) mannose- (C) galactose-, and (D) xylose-substituted analogues.

To date, over a hundred glycosyltransferases have been cloned1211. Expression and production in quantities sufficient for enzymatic synthesis is, however, another matter. Only a handful of glycosyltransferases are currently commercially available. Given the advantages of enzymatic synthesis of oligosaccharides over traditional schemes, research into the overexpression of glycosyltransferases will undoubtedly continue to be developed.
