Dv. Whittaker et al., STRUCTURAL ELUCIDATION OF THE CAPSULAR POLYSACCHARIDE PRODUCED BY ESCHERICHIA-COLI O20-K84-H26, Carbohydrate research, 262(2), 1994, pp. 323-334
The primary structure of the acidic capsular antigen produced by E. co
li K84 was shown by glycose and methylation analysis, and by 1D and 2D
H-1 and C-13 NMR studies of the polysaccharide and an oligosaccharide
produced by lithium-ethylenediamine degradation of the polysaccharide
, to be comprised of linear hexasaccharide repeating units of the foll
owing structure: c-(1-->2)-beta-D-Manp-(1-->3)-beta-D-ManpNAc-(1-->
