Structural studies of the capsular antigen from Streptococcus pneumoniae type 26

Carbohydrate Research

Abstract

The structure of the capsular antigen from Pneumococcus type 26 has been determined by using methylation analysis, periodate-oxidation studies, and n.m.r. spectroscopy of the original and the dephosphorylated product. It is considered that the polysaccharide is composed of repeating-units having the following structure. (formula: see text): The only difference between this structure and that of the type-6 antigen is that the alpha-L-rhamnopyranosyl residue is linked to O-4 of D-ribitol in the former, but to O-3 in the latter.
