ASCII Name[3)-alpha-D-Galp-(1->3)-beta-D-Galf2Ac-(1->]n
DefinitionA polysaccharide composed of a backbone of α-galactopyranosyl-(1→3)-galactofuranosyl repeating units that are joined to each other also via β-(1→3)-linkages; corresponds to the repeating unit of the O-specific polysaccharide from Plesiomonas shigelloides strain CNCTC 78/79, although in this species the O-acetylation is incomplete.
