Structural investigation of the capsular polysaccharide of Klebsiella serotype K35
摘要:
The structure of the capsular polysaccharide (K antigen) of Klebsiella K35 has been established as having the pentasaccharide repeating unit shown ("four plus one" type). The structural investigation utilized the techniques of methylation, beta-elimination, Smith degradation, and partial hydrolysis. N.m.r. spectroscopy (1H and 13C) was used extensively to establish the configurations of the anomeric linkages and to delineate the sequence of the sugars in the structure of the polysaccharide.

Klebsiellaserotype K53 is one of three strains belonging to the chemotype whose capsularpolysaccharides consist of D-glucuronic acid, D-galactose, D-mannose, and L-rhamnose residues, and the structure of its polysaccharide was found to be of the "5 + 1 type" shown, of the same structural pattern as the capsule from Klebsiella K52 (Formula, see text). Nimmich has analyzed the capsular polysaccharide
