The research focuses on the development of a chemoenzymatic method for the synthesis of aminodeoxy-α-D-glucopyranosyl and acetamidodeoxy-α-D-glucopyranosyl phosphate derivatives, which are important substrates for in vitro glycosylation systems. The researchers utilized Salmonella enterica LT2 α-D-glucopyranosyl phosphate thymidylyltransferase (E. coli) to phosphorylate and convert a range of synthetic substrates, including 1-ethylthio-β-D-pyranoside precursors, into the desired nucleotide sugars. The conclusions drawn from the study highlight the promiscuous nature of E. coli and its ability to accommodate various substrates, with the exception of those with bulky substituents at certain positions. The chemicals used in the process included various sugar phosphates, nucleotide triphosphates (NTPs), inorganic pyrophosphatase, and the enzyme E. coli itself, along with reagents for the synthesis and purification of the sugar phosphates, such as dibenzyl phosphate, sodium azide, and acetic anhydride.
