  Artificial N-functionalized UDP-glucosamine analogues as modified substrates for N-acetylglucosaminyl transferases

  摘要：

  Analogues of UDP-GlcNAc modified at the 2-acetamido group of the GlcNAc moiety were prepared in order to study their role in the mechanism of N-acetylglucosaminyl transferase mediated glycosylation reactions. The structural analogues with N-formyl-, N-propionyl-, N-butyryl- and N-isobutyryl-groups were synthesized, utilizing the morpholidate coupling method starting from D-glucosaminyl-1-phosphate after selective N-acylation of its amino group with the appropriate N-acyloxysuccinimide esters as well as a chlorinated formylformiate.

  A novel N-acetylglucosamine-1-phosphate pyrophosphorylase was identified from Campylobacter jejuni NCTC 11168. An unprecedented degree of substrate promiscuity has been revealed by systematic studies on its substrate specificities towards sugar-1-P and NTP. The yields of the synthetic reaction of seven kinds of sugar nucleotides catalyzed by the enzyme were up to 60%. In addition, the yields of the other nine were around 20%. With this enzyme, three novel sugar nucleotide analogs were synthesized on a preparative scale and well characterized. (C) 2013 Elsevier Ltd. All rights reserved.
