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