  • Title: Escherichia coli serotype-39 capsular polysaccharide: primary structure and depolymerisation by a bacteriophage-associated glycanase.
    Author: Parolis H, Parolis LA, Venter RD.
    Journal: Carbohydr Res; 1989 Feb 01; 185(2):225-32. PubMed ID: 2659169.
    Abstract:
    The acidic capsular polysaccharide isolated from Escherichia coli O9:K39:H9 was investigated, using n.m.r. spectroscopy, methylation analysis, uronic acid degradation of the native and methylated polysaccharides, and bacteriophage-associated enzyme degradation. The structure of the repeating unit, which is shown below, is identical to that reported for Klebsiella serotype-61 capsular polysaccharide. (formula; see text)
