Abstract
An acidic O-specific polysaccharide was obtained by mild acid degradation of the lipopolysaccharide isolated by phenol–water extraction of Pseudoalteromonas haloplanktis strain KMM 223 (44-1). l-Iduronic acid (IdoA) was found to be a component of the polysaccharide and identified by NMR spectroscopy and after carboxyl-reduction followed by acid hydrolysis and acetylation, by GLC-MS as 2,3,4-tri-O-acetyl-1,6-anhydroidose. On the basis of 1H and 13C NMR spectroscopic studies, including 1D NOE, 2D NOESY, HSQC and HMBC experiments, the following structure of the branched pentasaccharide repeating unit of the polysaccharide was established:
