Structure of the group G streptococcal polysaccharide.
The structure of the group-specific polysaccharide of group G Streptococcus was determined by means of methylation analysis and selective chemical degradations. The anomeric configurations and conformations of the sugar residues were studied by 1H- and 13C-n.m.r. spectroscopy. The tetrasaccharide repeating unit, ----3)-alpha-D-Galp-(1----2)-[alpha-L-Rhap-(1----3)-beta-D-GalpNAc - (1----4)]-alpha-L-Rhap-(1----, was determined.
