Structural studies of the Escherichia coli O78 O-antigen polysaccharide.
The structure of the O-antigen polysaccharide from Escherichia coli O78 has been investigated; methylation analysis, partial solvolysis with liquid hydrogen fluoride, and 2D-n.m.r. spectroscopy were the principal methods used. It is concluded that the polysaccharide is composed of tetrasaccharide repeating-units having the following structure.----3)-beta-D-GlcpNAc-(1----4)-beta-D-GlcpNAc- (1----4)-beta-D-Manp-(1----4)-alpha-D-Manp-(1----
