Mr. Grue et al., ESCHERICHIA-COLI SEROTYPE K-45 CAPSULAR ANTIGEN - A GLYCAN CONTAINING3-ACETAMIDO-3,6-DIDEOXYGALACTOPYRANOSE, Carbohydrate research, 248, 1993, pp. 191-198
The primary structure of the acidic capsular antigen of Escherichia co
li O8:K45:H9 was shown by glycose analysis, methylation analysis, and
one- and two-dimensional H-1 and C-13 NMR spectroscopy to be composed
of repeating branched tetrasaccharide units having the structure: [GRA
PHICS] The polysaccharide contains the uncommon amino sugar 3-acetamid
o-3,6-dideoxy-D-galactopyranose, which has not been previously identif
ied in a capsular antigen.
