Instead of building up the sugar nucleotide from the free sugar itself, nature often chooses to modify the "donor" portion of a pre-existing sugar nucleotide in a biosynthetically efficient manner. In doing so a rich variety of catalytic strategies are employed and this review focuses on recent mechanistic and structural studies of the sugar nucleotide-modifying enzymes. The review is organized around the types of reactions catalyzed and contains the following sections: Epimerases/Mutases/Decarboxylases, Eliminations and Substitutions, Oxidation and Reduction, and Substitutions on the Periphery of Sugar Nucleotides.}, keywords = {4, 6-DEHYDRATASE, 6-DIDEOXYHEXOSES, ACETYLGLUCOSAMINE 2-EPIMERASE/N-ACETYLMANNOSAMINE, ACETYLNEURAMINIC ACID, biosynthesis, CYTIDINE DIPHOSPHATE 3, D-GLUCOSE, ESCHERICHIA-COLI K-12, FIRST 2, GDP-FUCOSE SYNTHETASE, KINASE, N-ACETYLGLUCOSAMINE, SITE-DIRECTED MUTAGENESIS, STEPS, UDP-GALACTOSE 4-EPIMERASE}, isbn = {1385-2728}, url = {://000167487300004}, author = {Tanner, M.
