The intercellular adhesin involved in biofilm accumulation of Staphylococcus epidermidis is a linear beta-1,6-linked glucosaminoglycan: purification and structural analysis
The primary attachment to polymer surfaces followed by accumulation in multilayered cell clusters leads to biofilm production of Staphylococcus epidermidis, which is thought to contribute to
Teichoic acid and lipoteichoic acid of Streptococcus pneumoniae possess identical chain structures. A reinvestigation of teichoid acid (C polysaccharide).
On the basis of compositional analysis, fast-atom-bombardment mass spectrometry and NMR spectroscopy the following structure is proposed: teichoic acid (C polysaccharide) where AATGal is 2-acetamido-4-amino-2,4,6-trideoxy-D-galactose and the repeating units are linked to each other by phosphodiester bonds.
The structure of pneumococcal lipoteichoic acid. Improved preparation, chemical and mass spectrometric studies.
Pneumococcal lipoteichoic acid was extracted and purified by a novel, quick and effective procedure and preliminary results suggest that repeating units II and IV are enriched in separate molecular species.
Structural analysis of glycosphinoglipids by high-resolution 1H nuclear magnetic resonance spectroscopy.
Regularities related to the type, anomeric configuration, site of glycosidic linkage, and sequence of the component sugars glucose, galactose, glucosamine, and galactosamine are suited for elucidation of hitherto unknown structure of more complex glycosphingolipids.
High-pH anion-exchange chromatography with pulsed amperometric detection and molar response factors of human milk oligosaccharides.
The moral response factors after HPAEC-PAD have been determined for 28 components and the neutral and acidic components were separated from each other by anion-exchange chromatography.
Purification and structures of branched blood-group-B-active glycosphingolipids from human erythrocyte membranes.
Three different variants of complex, branched, highly blood-group-B-active glycosphingolipids have been isolated from human erythrocytes and the nature of the anomeric linkages and branching points of B-V was established based upon the series of NMR data obtained from the B-I--B-IV analogues.
Structural determination of N-2'-hydroxyoctadecenoyl-1-O-beta-D-glucopyranosyl-9-methyl-4, 8-sphingadienine from species of Aspergillus.
Although the structures presently described are similar to those of monohexosylceramides from other fungi, including edible ones, this is the first report on their occurrence in species pathogenic in humans.
Immunochemistry of the Lewis-blood-group system: proton nuclear magnetic resonance study of plasmatic Lewis-blood-group-active glycosphingolipids and related substances.
Some deviations from additivity in chemical shifts, calculated for oligosaccharides from the data on their constituent sugar residues, furnished information on the conformational changes in crowded glycolipid molecules.
