The role of C-4-substituted mannose analogues in protein glycosylation. Effect of the guanosine diphosphate esters of 4-deoxy-4-fluoro-D-mannose and 4-deoxy-D-mannose on lipid-linked oligosaccharide assembly.
The effects of the guanosine diphosphate esters of 4-deoxy-4-fluoro-D-mannose (GDP-4FMan) and 4-deoxy-D-mannose (GDP-4dMan) on reactions of the dolichol pathway in chick-embryo cell microsomal membranes were investigated by studies with chick-embryo cell microsomal membranes in vitro and in baby-hamster kidney (BHK) cells in vivo. Each nucleotide sugar analogue inhibited lipid-linked oligosacch...
متن کاملCharacterization of 3-O-methyl-D-mannose polysaccharide precursors in Mycobacterium smegmatis.
Mycobacterium smegmatis, when incubated under appropriate conditions with L-[methyl-Tlmethionine, accumulates significant amounts of small [methyl-T]-labeled oligosaccharides that are related to the known 3O-methyl-D-mannose polysaccharides (Maitra, S. K., and Ballou, C. E. (1977) J. Biol. Chem. 252, 2459-2469). We have fractionated the water-soluble material from the 70% ethanol extract of suc...
متن کاملThe Occurrence of D-mannose in Seaweed and the Separation of L-fucose and D-mannose.*
The wide-spread occurrence of mannans and fucosans in nature makes it not improbable that some of these vegetable gums may in fact consist in part at least of fuco-mannans. In general the isolation and identification of two or more sugars from a mixture is often fraught with experimental difficulties, particularly if the material is available only in small amounts. Any simple procedure applicab...
متن کاملEfficient acquisition of high-resolution 4-D diagonal-suppressed methyl-methyl NOESY for large proteins.
The methyl-methyl NOESY experiment plays an important role in determining the global folds of large proteins. Despite the high sensitivity of this experiment, the analysis of methyl-methyl NOEs is frequently hindered by the limited chemical shift dispersion of methyl groups, particularly methyl protons. This makes it difficult to unambiguously assign all of the methyl-methyl NOE crosspeaks usin...
متن کاملSynthesis and Molecular Structure of Methyl 4-O-methyl-α-D- glucopyranuronate
A method for the preparation of methyl 4-O-methyl-α-D-glucopyranuronate and its single crystal X-ray structure determination are reported. The molecule adopts an almost ideal C1 (C3) conformation.
