Term Name:	S. flexneri serotype 6 O-polysaccharide (O factor 9-positive)
Synonyms:	[2)-alpha-L-Rha(III)3/4Ac-(1->2)-alpha-L-Rha(II)-(1->4)-beta-D-GalA-(1->3)-beta-D-GalNAc-(1->]n, [2)-alpha-L-Rha(III)p3/4Ac-(1->2)-alpha-L-Rha(II)p-(1->4)-beta-D-GalpA-(1->3)-beta-D-GalpNAc-(1->]n
Definition:	A polysaccharide derivative comprised of a [2)-alpha-L-Rhap(III)-(1->2)-alpha-L-Rhap(II)-(1->3)-beta-D-GalpA-(1->3)-beta-D-GalpNAc-(1->] tetrasaccharide repeat modified by the addition of an acetyl group to either O-3 or O-4 of many of the Rha(III) residues (60% to O-3; 30% to O-4). The structure provided is representative of that in Shigella flexneri serotype 6 and shows the most common repeating unit.
