Abstract:
The capsular polysaccharide of A. pleuropneumoniae is composed of 2-acetamido-2-deoxy-D-glucose (3 parts) and phosphate (1 part). The arrangement of these components in the repeating unit was determined by dephosphorylation, methylation, g.l.c.-m.x., and 1D and 2D n.m.r. spectroscopic methods. The polysaccharide was found to be a high molecular weight polymer of repeating trisaccharide units, joined through phosphate diester linkages, having the structure, (formula: see text).
