Abstract:
The linkage pattern of the K6-antigen was investigated using material from the urinary pathogen, LP 1092. The polysaccharide consists of ribose and 3-deoxy--2-octulosonate (KDO) in a ratio of 2:1. Colorimetric procedures, Smith degradation, methylation analysis, and nuclear magnetic resonance spectroscopy were applied to the whole polysaccharide and to a trisaccharide “repeating unit” obtained by mild-acid catalyzed hydrolysis. Together, the data are compatible only with a branched chain structure ……
