The O-chain polysaccharide produced by Proteusmirabilis strain 7570 was shown by chemical analysis and 1D and 2D NMR spectroscopy to be a high molecular weight acidic linear polymer of tetrasaccharide repeating units, composed of D-galacturonic acid, 2-acetamido-2-deoxy-D-galactose, and 2-acetamido-2-deoxy-D-glucose (2:1:1). In addition, native O-chain was randomly substituted by O-acetyl groups. Keywords: Proteus, lipopolysaccharide, O-chain, structure, NMR.
