title: Structure of the phenol-soluble polysaccharide from Shewanella putrefaciens strain A6.
abstract: The structure of the phenol-soluble polysaccharide from Shewanella putrefaciens strain A6 has been elucidated. Chemical modifications of the polymer in conjunction with 1H and 13C NMR spectroscopy, including 2D techniques, were employed in the analysis. It is concluded that the repeating unit is composed of two nine-carbon sugars as follows: -->4)-alpha-NonpA-(2-->3)-beta-Sugp-(1--> where alpha-NonpA is 5-acetamido-7-acetamidino-8-O-acetyl-3,5,7,9-tetradeoxy-L-glycero-alpha-D-galacto-non-2-ulosonic acid (8eLeg) and beta-Sugp is 2-acetamido-2,6-dideoxy-4-C-(3'-carboxamide-2',2'-dihydroxypropyl)-beta-D-galactopyranose, with the proposed name Shewanellose (She).
