Update on Nucleotide Sugar Synthesis UDP-Sugar Pyrophosphorylase: A New Old Mechanism for Sugar Activation
Simple sugars (e.g. Glc, Gal) are the building blocks of disaccharides (e.g. Suc) and polysaccharides (e.g. cellulose, hemicellulose). To produce disaccharides and polysaccharides, a given simple sugar needs to be “activated.” This activation involves the addition of a nucleoside-diphosphate group to a sugar, resulting in the formation of a nucleotide sugar. Such an activated sugar can then be ...
متن کاملPlant nucleotide sugar formation, interconversion, and salvage by sugar recycling.
Nucleotide sugars are the universal sugar donors for the formation of polysaccharides, glycoproteins, proteoglycans, glycolipids, and glycosylated secondary metabolites. At least 100 genes encode proteins involved in the formation of nucleotide sugars. These nucleotide sugars are formed using the carbohydrate derived from photosynthesis, the sugar generated by hydrolyzing translocated sucrose, ...
متن کاملUnderstanding low sugar from NICE-SUGAR.
n engl j med 367;25 nejm.org december 20, 2012 2449 migraine and headache were collected separately. Of the 800 patients treated with enzalutamide, 3 (0.4%) were reported to have had a migraine. Headaches were reported in 93 patients treated with enzalutamide (11.6%) and in 22 of the 399 patients treated with placebo (5.5%). In the enzalutamide group, the majority of reports were for grade 1 he...
متن کاملSubcellular localization of sugar nucleotide synthetases.
Sugar nucleotides are Drecursors of sugar moieties in obtained bv others in brain and kidney (Gielen et al., 1970 glycGlipids and glycoproteins and thus may have a regulatory role in the metabolism of these macromolecules. We have therefore studied the subcellular localization of four sugar nucleotide synthetases. The pyrophosphorylases of GDP-fucose, GDP-mannose, and UDP-glucose were detected ...
متن کاملEvolution of Plant Nucleotide-Sugar Interconversion Enzymes
Nucleotide-diphospho-sugars (NDP-sugars) are the building blocks of diverse polysaccharides and glycoconjugates in all organisms. In plants, 11 families of NDP-sugar interconversion enzymes (NSEs) have been identified, each of which interconverts one NDP-sugar to another. While the functions of these enzyme families have been characterized in various plants, very little is known about their evo...
