Biosynthesis of Guanosine Diphosphate D-Rhamnose and Guanosine Diphosphate D-Talomethylose from Guanosine Diphosphate a-*Mannose*
Strain GS, a gram-negative motile bacterium isolated from soil, synthesizes two polysaccharides. The synthesis of a uranic acid-containing polysaccharide is derepressed by high concentrations of Na2SOd, while the synthesis of the polysaccharide containing equal quantities of n-rhamnose and n-talomethylose is repressed by NazS01 (1, 2). L-F’ucose and L-rhamnose are the methylpentoses commonly fo...

متن کاملFormation of guanosine diphosphate L-fucose from guanosine diphosphate D-mannose.
The 6-deoxyhexose, L-fucose, has a wide distribution in nature as a component of bacterial, plant, and animal polysaccharides or oligosaccharides. Its configuration, which is the same as Lgalactose, suggested to earlier workers that it might be formed biosynthetically from n-galactose by reduction of C-l to a methyl group and oxidation of C-6 to an aldehyde. This suggestion was rendered untenab...

متن کاملThe Synthesis of Guanosine 5'-Diphosphate l-Fucose from Guanosine 5'-Diphosphate 3,5-d-[H]Mannose Catalyzed by an Enzyme Extract from Fruits of the Flax.
An enzyme system from fruits of the flax plant is described that catalyzes the synthesis of the sugar nucleotide guanosine 5'-diphosphate l-fucose from guanosine 5'-diphosphate d-mannose with the intermediate formation of guanosine 5'-diphosphate 4-keto-6-deoxy-d-mannose. Tritium from-[(3)H]H(2)O was incorporated into the l-fucose portion of the sugar nucleotide in the course of the reaction, a...
