AI Article Synopsis
- The structure of a phenol-soluble polysaccharide from Pseudoalteromonas rubra was determined through various NMR spectroscopy techniques.
- The repeating unit of the polysaccharide is identified as a trisaccharide consisting of unique carbohydrate components.
- Approximately 70% of the units are O-acetylated, featuring specific residues such as 2-acetamido-2,6-dideoxy-D-xylo-hexos-4-ulose, acetimidoyl, and malic acid.
Article Abstract
The structure of the phenol-soluble polysaccharide from Pseudoalteromonas rubra type strain ATCC 29570T has been elucidated using 1H and 13C NMR spectroscopy, including 2D COSY, TOCSY, gNOESY, ROESY, 1H,13C gHMQC and gHMBC experiments. It is concluded that the trisaccharide repeating unit of the polysaccharide has the following structure: [carbohydrate structure: see text] where Sug is 2-acetamido-2,6-dideoxy-D-xylo-hexos-4-ulose, Am is acetimidoyl and Acyl is a malic acid residue, which is O-acetylated in approximately 70% of the units.
