H. Yildirim et al., Structural studies of the O-polysaccharide from the Escherichia coli O77 lipopolysaccharide, CARBOHY RES, 333(2), 2001, pp. 179-183
The structure of the O-antigen polysaccharide (PS) from Escherichia coli O7
7 has been determined. Sugar and methylation analysis together with H-1 and
C-13 NMR spectroscopy were the main methods used. The PS is composed of te
trasaccharide repeating units with the following structure:
--> 2)-alpha -D-Manp-(1 --> 2)-beta -D-ManP-(1 --> 3)-alpha -D-GlcpNAc-(1 -
-> 6)-alpha -D-Manp-(1 -->
