متن کاملGlycans from Streptococcal Cell Walls
The cell wall of Streptococcus faecalis, strain N, has been found to contain two antigenic glycans, a diheteroglycan of glucose and galactose and a tetraheteroglycan of rhamnose, glucose, galactose, and N-acetylgalactosamine. The present report describes the isolation, purification, and structural and immunochemical characterization of the hitherto unknown diheteroglycan. A tentative structure ...
متن کاملStructure of Streptococcal Cell Walls. 3. Characterization of an Alanine-containing Glucosaminylmuramic Acid Derivative Liberated by Lysozyme from Streptococcal Glycopeptide.
A glycopeptide (also called mucopeptide) fraction of bacterial cell walls, believed to be associated with shape and structural stability of microorganisms, may, in the case of Group A streptococci, be isolated with relative ease as the formamide-insoluble residue of protease-treated cell walls (1). Analyses and certain susceptibilities to enzymic lysis of this fraction have been reported (1, 2)...
متن کاملStructure of Streptococcal Cell Walls. Ii. Group a Biose and Group a Triose from C-polysaccharide.
On the basis of evidence presented or cited in a previous article (see Reference 1 for Paper I), the group-specific C-polysaccharide of Group A hemolytic streptocci is a polymer of L-rhamnose and N-acetyl-n-glucosamine in which the methylpentose units occur as 3and 2,3-substituted, a-linked saccharides with terminal P-linked hexosamine molecules and possibly intracatenary hexosamine. The study ...
متن کاملBiosynthesis of streptococcal cell walls: N-acetyl-D-muramic acid.
Glucose-1-(14)C and acetylglucosamine-1-(14)C were added singly and together with equal amounts of the unlabeled reciprocal to Brain Heart Infusion and used for the culture of Streptococcus pyogenes. The labeling pattern of the rhamnose, glucosamine, and muramic acid in the cell wall supported an intermediary role for acetylglucosamine in providing the C1-C6 moiety of muramic acid. Although rad...
