title: Two-step enzymatic synthesis of UDP-N-acetylgalactosamine.
abstract: UDP-GalNAc has been synthesised with high yield from GalNAc, UTP and ATP using recombinant human GalNAc kinase GK2 and UDP-GalNAc pyrophosphorylase AGX1. Both enzymes have been prepared in one step from 1L cultures of transformed Escherichia coli and the UDP-GalNAc produced has been purified by a simple procedure. The method described is a rapid and efficient means to produce UDP-GalNAc as well as analogues like UDP-N-azidoacetylgalactosamine (UDP-GalNAz).
