Structure of the O-specific polysaccharide from a marine bacterium Cellulophaga pacifica containing rarely occurred sugars, Fuc4NAc and ManNAcA

The O-polysaccharide was isolated from the lipopolysaccharide of Cellulophaga pacifica and studied by chemical methods including Smith degradation as well as 1H and 13C NMR spectroscopy. The following structure of the O-polysaccharide of Cellulophaga pacifica containing N-acetyl-d-glucosamine (GlcNAc), 4-acetamido-4,6-dideoxy-d-galactose (Fuc4NAc) and two residues of 2-acetamido-2-deoxy-d-mannuronic acid (ManNAcA) was established.Figure optionsDownload as PowerPoint slide
