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 transfer of mannose from guanosine diphosphate mannose to dolichol phosphate and protein by pig liver endoplasmic reticulum.
When pig liver microsomal preparations were incubated with GDP-[(14)C]mannose, 10-40% of the (14)C was transferred to mannolipid and 1-3% to mannoprotein. The transfer to mannolipid was readily reversible and GDP was one of the products of the reaction. It was possible to reverse the reaction by adding excess of GDP and to show the incorporation of [(14)C]GDP into GDP-mannose. When excess of un...
متن کاملSubcellular localization of the enzyme that forms mannosyl retinyl phosphate from guanosine diphosphate [14C]mannose and retinyl phosphate.
The subcellular distribution of the enzyme catalysing the conversion of retinyl phosphate and GDP-[14C]mannose into [14C]mannosyl retinyl phosphate was determined by using subcellular fractions of rat liver. Purity of fractions, as determined by marker enzymes, was 80% or better. The amount of mannosyl retinyl phosphate formed (pmol/min per mg of protein) for each fraction was: rough endoplasmi...
