label: P. mirabilis 9B-m O-specific polysaccharide
label_lc: p. mirabilis 9b-m o-specific polysaccharide
description: "A polysaccharide derivative consisting of a repeating unit of beta-D-glucuronosyl, beta-D-galacturonosyl and N-acetyl-beta-D-glucosaminyl residues linked sequentially (1->3) and (1->3), to the glucuronosyl residue of which is linked (1->2) an N-acetyl-beta-D-glucosaminyl residue, while the galacturonosyl residue forms an amide with L-threonine, the complete tetrasaccharide repeating units all being linked (1->4). The O-polysaccharide of Proteus mirabilis 9B-m."
