{Reference Type}: Journal Article {Title}: The structure of O-polysaccharide isolated from the type strain of Pectobacterium versatile CFBP6051T containing an erwiniose - higher branched monosaccharide. {Author}: Kowalczyk A;Babińska-Wensierska W;Lojkowska E;Kaczyński Z; {Journal}: Carbohydr Res {Volume}: 524 {Issue}: 0 {Year}: Feb 2023 {Factor}: 2.975 {DOI}: 10.1016/j.carres.2023.108743 {Abstract}: Utilizing sugar, methylation, and absolute configurations analyses as well as NMR spectroscopy, the chemical repeating unit of the O-specific polysaccharide of Pectobacteriumversatile CFBP6051T was identified as: The polymer contains residues of an unusual, higher-branched monosaccharide, named erwiniose (3,6,8-trideoxy-4-C-(R-1-hydroxyethyl)-d-gulo-octose). Comparison of the P. versatile CFBP6051T O-polysaccharide with those isolated from strains of other Pectobacterium species indicated high differentiation in their structures within this genus.
