Efficient enzymatic synthesis of guanosine 5'-diphosphate-sugars and derivatives.

An N-acetylhexosamine 1-kinase from Bifidobacterium infantis (NahK_15697), a guanosine 5'-diphosphate (GDP)-mannose pyrophosphorylase from Pyrococcus furiosus (PFManC), and an Escherichia coli inorganic pyrophosphatase (EcPpA) were used efficiently for a one-pot three-enzyme synthesis of GDP-mannose, GDP-glucose, their derivatives, and GDP-talose. This study represents the first facile and efficient enzymatic synthesis of GDP-sugars and derivatives starting from monosaccharides and derivatives.
