Glucose-1-phosphate thymidylyltransferase (Cps23FL) from Streptococcus pneumonia serotype 23F is the initial enzyme that catalyses the thymidylyl transfer reaction in prokaryotic deoxythymidine diphosphate-l-rhamnose (dTDP-Rha) biosynthetic pathway. In this study, the broad substrate specificity of Cps23FL towards six glucose-1-phosphates and nine nucleoside triphosphates as substrates was systematically explored, eventually providing access to nineteen sugar nucleotide analogs.

In recent years, the development of the enzymatic bioorthogonal labeling strategy has offered exciting possibilities in the probing of structure-defined glycan epitopes. This strategy takes advantage of relaxed donor specificity and strict acceptor specificity of glycosyltransferases to label target glycan epitopes with bioorthogonal reactive groups carried by unnatural nucleotide sugars in vitro. The subsequent covalent conjugation by bioorthogonal chemical reactions with either fluorescent or affinity tags allows further visualization, quantification, or enrichment of target glycan epitopes. However, the application and development of the enzymatic labeling strategy have been hindered due to the limited availability of unnatural nucleotide sugars. Herein, a platform that combines chemical synthesis and enzymatic synthesis for the facile preparation of unnatural nucleotide sugars modified with diverse bioorthogonal reactive groups is described. By this platform, a total of 25 UDP-GlcNAc and UDP-GalNAc derivatives, including the most well explored bioorthogonal functional groups, were successfully synthesized. Furthermore, the potential application of these compounds for use in enzymatic bioorthogonal labeling reactions was also evaluated.

Glucose-1-phosphate uridylyltransferase in conjunction with UDP-glucose pyrophosphorylase was found to catalyse the conversion of a range of 5-substituted UTP derivatives into the corresponding UDP-galactose derivatives in poor yield. Notably the 5-iodo derivative was not converted to UDP-sugar. In contrast, UDP-glucose pyrophosphorylase in conjunction with inorganic pyrophosphatase was particularly effective at converting 5-substituted UTP derivatives, including the iodo compound, into a range of gluco-configured 5-substituted UDP-sugar derivatives in good yields. Attempts to effect 4″-epimerization of these 5-substituted UDP-glucose with UDP-glucose 4″-epimerase from yeast were unsuccessful, while use of the corresponding enzyme from Erwinia amylovora resulted in efficient epimerization of only 5-iodo-UDP-Glc, but not the corresponding 5-aryl derivatives, to give 5-iodo-UDP-Gal. Given the established potential for Pd-mediated cross-coupling of 5-iodo-UDP-sugars, this provides convenient access to the galacto-configured 5-substituted-UDP-sugars from gluco-configured substrates and 5-iodo-UTP.

A promiscuous UDP-sugar pyrophosphorylase (BLUSP) was cloned from Bifidobacterium longum strain ATCC55813 and used efficiently with a Pasteurella multocida inorganic pyrophosphatase (PmPpA) with or without a monosaccharide 1-kinase for one-pot multienzyme synthesis of UDP-galactose, UDP-glucose, UDP-mannose, and their derivatives. Further chemical diversification of a UDP-mannose derivative resulted in the formation of UDP-N-acetylmannosamine. The Royal Society of Chemistry 2012.

A Pasteurella multocida N-acetylglucosamine 1-phosphate uridylyltransferase (PmGlmU) was cloned and used efficiently with an N-acetylhexosamine 1-kinase (NahK-ATCC55813) and an inorganic pyrophosphatase (PmPpA) for one-pot three-enzyme synthesis of UDP-GlcNAc derivatives with or without further chemical diversification.

(Graph Presented) Enzymatic approaches to prepare sugar nucleotides are gaining in importance and offer several advantages over chemical synthesis including high yields and stereospecificity. We report the cloning, expression, and purification of two new wild-type thymidylyltransferases and observed catalysis with a wide variety of substrates. Significant product inhibition was not observed with the enzymes studied over a 24 h period, enabling the efficient preparation of 15 sugar nucleotides, clearly demonstrating the synthetic utility of these biocatalysts.
