Complete structure of the polysaccharide from Streptococcus sanguis J22

Biochemistry, 1990
The cell wall polysaccharides of certain oral streptococci such as Streptococcus sanguis strains 34 and J22, although immunologically distinct, act as receptors for the fimbrial lectins of Actinomyces viscosus T14V. We report the complete covalent structure of the polysaccharide from S.

J22 Registry To Enroll-hd: Transition In Europe And The Founding Of A New Research Platform

Journal of Neurology, Neurosurgery & Psychiatry, 2014
Background Enroll-HD, a global longitudinal observational study has been established to provide a research platform and clinical data set to support research into the aetiology of Huntington’s disease (HD) and accelerate the development of novel therapeutics. In June 2012 the first patient was recruited to the study in North America.

Non-existence of rational integrals in the J22-problem

Physics Letters A, 1995
Abstract In this paper we establish the non-existence of additional global rational integrals for a satellite problem, only under the perturbation of the main sectorial term, J 22 , by using methods based on some theorems by Yoshida and Ziglin.

Molecular Modeling of the Flexible Cell Wall Polysaccharide of Streptococcus mitis J22 on the Basis of Heteronuclear NMR Coupling Constants

Biochemistry, 1996
A method for constructing conformational models of flexible complex polysaccharides on the basis of NMR data and molecular modeling is described and is applied to a polysaccharide which is a lectin-binding receptor important in coaggregation of oral bacteria.

Measurement of long‐range2 13C‐1H coupling constants of 95% uniformly 13C‐labeled polysaccharide from streptococcus mitis J22

Biopolymers, 1994
AbstractThe coaggregation of Streptococcus mitis strain J22 in the early stages of dental plaque formation has been shown to result from interaction of cell wall polysaccharides with lectins on the surface of other oral bacterial species. This bacterium was grown in a medium containing 13C as the sole carbon source. We have isolated the lectin receptor

The cell wall polysaccharide of Streptococcus gordonii 38: structure and immunochemical comparison with the receptor polysaccharides of Streptococcus oralis 34 and Streptococcus mitis J22

Glycobiology, 1994
As part of our ongoing investigations involving lectin-mediated adhesion among oral bacteria, the receptor polysaccharide from Streptococcus gordonii 38 was isolated and characterized. Carbohydrate analysis of the hydrolysed S. gordonii 38 polysaccharide by high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD ...

A flexible model for the cell wall polysaccharide of Streptococcus mitis J22 determined by three‐dimensional 13C edited nuclear overhauser effect spectroscopy and 13C‐1H long‐range coupling constants combined with molecular modeling

Biopolymers, 1996
We report on the conformation of a tetrasaccharide fragment in the repeating subunit of the cell wall polysaccharide of Streptococcus mitis J22, a receptor for the lectin of Actinomyces viscosus T14V in a bacterial coaggregation that is important in the ecological interactions of oral bacteria.
