A CORE OLIGOSACCHARIDE COMPONENT FROM SACCHARIDE OF Rhizobium trifolii ANU843
The major oligosaccharide from the core region of the lipopolysaccharide from R. trifolii ANU843 was isolated and its structure determined. It is a trisaccharide consisting of two galacturonic acid residues and one 3-deoxy-D-manno2octulosonic acid (KDO) residue. The two galacturonic acid residues are terminally linked alpha to the C-4 and C-7 atoms of KDO. This structure was determined through ...
متن کاملThe complete structure of the trifoliin A lectin-binding capsular polysaccharide of Rhizobium trifolii 843.
The complete structure of the acidic, extracellular, capsular polysaccharide of Rhizobium trifolii 843 has been elucidated by a combination of chemical, enzymic, and spectroscopic methods, confirming an earlier proposed sugar sequence and assigning the locations of the acyl substituents. The polysaccharide was depolymerized by a lyase into octasaccharide units which were uniform in carbohydrate...
متن کاملRoot Hair Deformations Associated with Fractionated Extracts from Rhizobium trifolii.
Components from culture fluid and whole cells of Rhizobium trifolii were examined for effects on root hair morphology of white clover seedlings (Trifolium repens var. Ladino). Cell-free culture fluid, exopolysaccharides, supernatant fluid from the precipitation of the exopolysaccharides, capsular polysaccharides, lipopolysaccharides, and a protein fraction from culture fluids were assayed for m...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولStudies on the Aspartic Acid Decarboxylase of Rhizobium Trifolii.
Virtanen and Laine (1937) were the first to suggest the existence of an aspartic acid decarboxylase in Rhizobium trifolii, by the isolation of beta-alanine from a 47-day fermentation mash containing aspartic acid. Shive and Macow (1946), working with hydroxyaspartic acid as a competitive analogue for aspartic acid in the metabolism of Escherichia coli, found that the addition of this compound t...
