A Simple Synthesis of Sugar Nucleoside Diphosphates by Chemical Coupling in Water
Angewandte Chemie International Edition, 2012The use of glycosyltransferases in chemoenzymatic oligosaccharide synthesis is attractive, provided that the enzymes are available, since it eliminates the tedious multistep protectiondeprotection and chemical glycosylation procedure that characterizes classic chemical synthesis.

An improved method for the isolation of some nucleoside diphosphate sugars from yeast
Biochimica et Biophysica Acta, 1957Abstract An improved method is described for the simultaneous isolation of UDPG, UDPAG and GDPM from yeast. The method involves extraction with ethanol and chromatography on anion exchange resin columns. The nucleotides are obtained from the effluent by adsorption on charcoal and subsequent elution with aqueous ethanol. A washing of the charcoal with

The reaction mechanism of the phosphoryl transfer catalyzed by dinucleoside diphosphate kinase from Dictyostelium discoideum is investigated by semiempirical AM1 molecular orbital computation of an active site model system on the basis of various X-ray crystallographic structures.

Publisher Summary This chapter discusses the synthesis of sugar nucleotide phosphorylases from yeast and from wheat germ. In the assay method for yeast, the reaction is carried out using guanosine diphosphate (GDP) mannose and 32 P. The radioactive GDP produced during incubation is separated from 32 P i by adsorption on charcoal.

Pyrophosphates are central to biology, and synthetic pyrophosphate isosteres are widely sought to create biomimetic molecules to study diverse biochemical processes. We describe a flexible, modular synthesis of nucleoside diphosphate sugar analogues by linking carbasugars and nucleosides with the dual electrophilic reagents chlorosulfonyl isocyanate ...
