Structural studies of capsular polysaccharide of type XII diplococcus pneumoniae
(Elsevier, 1974-10)
The capsular polysaccharide of Diplococcus pneumoniae Type XII contains residues of -glucose and -galactose in a molar ratio of 2:1. The methylated polysaccharide yielded upon hydrolysis 2,3,4,6-tetra- and 3,4,6-tri-O-me ...
2-acetamido-2-deoxy-[alpha]-D-galactosidases of clostridium perfringens. separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]-D-galactosidases have been separated from filtrates of cultured Clostridium perfringens by electrophoresis in 6.5% poly(acryl-amide) gels. One of the enzymes had a mobility of ...
2-acetamido-2-deoxy-[alpha]--galactosidases of clostridium perfringens. Separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]--galactosidases have been separated from filtrates of cultured Clostridium perfringens by electrophoresis in 6.5 % poly(acryl-amide)gels. One of the enzymes had a mobility of 0.32-0.36 ...
Protein---carbohydrate interaction. : Part XXII. A chemically-synthesized d-mannan and the interaction of some synthetic d-mannans with concanavalin A
(Elsevier, 1970-06)
1,6-Anhydro-[beta]--mannopyranose was polymerized in the presence of chloroacetic acid. A high-molecular-weight fraction insoluble in 80% ethanol was isolated and studied. Periodate-oxidation studies showed the polymer to ...
Synthesis of p-nitrophenyl 2-O-[alpha]--mannopyranosyl-[alpha]--mannopyranoside and p-nitrophenyl 6-O-[alpha]--mannopyranosyl-[alpha]--mannopyranoside
(Elsevier, 1979-12)
Crystalline 2-O-[alpha]--mannopyranosyl-[beta]--mannopyranose octaacetate was synthesized by condensation of tetra-O-acetyl-[alpha]--mannopyranosyl bromide (3) with 1,3,4,6-tetra-O-acetyl-[beta]--mannopyranose. ...
Gas-liquid chromatography of carbohydrate derivatives: the separation and quantitative determination of synthetic and naturally occurring glycosyl derivatives of amino acids
(Elsevier, 1972-05)
A gas-liquid chromatographic separation of the trimethylsilyl derivatives of several synthetic and naturally occurring glycosyl derivatives of amino acids is described. This technique may be used for the qualitative and ...
Preparation of cyrstalline [alpha]-kojibiose octaacetate from dextran B-1299-S: Its conversion into p-nitrophenyl and p-isothiocyanatophenyl [beta]-kojibioside
(Elsevier, 1973-03)
Acetolysis of dextran B-1299-S provides a preparative approach to crystalline [alpha]-kojibiose octaacetate. The latter was transformed via crystalline hepta-O-acetyl-[alpha]-kojibiosyl bromide into p-nitrophenyl and ...
Interaction of pneumococcal S-14 polysaccharide with lectins from Ricinus communis, Triticum vulgaris, and bandeiraea simplicifolia
(Elsevier, 1977-09)
Two purified lectins, namely, wheat-germ agglutinin (from Triticum vulgaris) and the hemagglutinin from Ricinus communis seeds, readily form a precipitate with pneumococcal S-14 polysaccharide, whereas the Bandeiraea ...
Equilibrium dialysis and carborydrate-binding studies on the 2-acetamido-2-deoxy--glucopyranosyl-binding lectin from bandeiraea simplicifolia seeds
(Elsevier, 1978-03)
The carbohydrate-binding specificity of Bandeiraea simplicifolia lectin II (BS II lectin) has been studied by quantitative precipitin and hapten-inhibition analysis. The BS II lectin precipitated biopolymers having nonreducing ...
