Figure 1From: The capsule polysaccharide structure and biogenesis for non-O1 Vibrio cholerae NRT36S: genes are embedded in the LPS regionPanel A shows the HSQC spectrum of the de-O-acetylated capsular polysaccharide from NRT36S. The strong signal at 3.78, 60 ppm is a low molecular weight impurity. Panel B shows the signal from the anomeric region. The methyl group region is not shown.Back to article page
