title: Structure of the O-specific polysaccharide of the bacterium Proteus mirabilis O29.
abstract: An O-specific polysaccharide was obtained by mild acid degradation of P. mirabilis O29 lipopolysaccharide (LPS) and found to contain 2-acetamido-2-deoxy-D-galactose and D-glucuronic acid (D-GlcA) in the ratio 3:1. Studies of the polysaccharide by 1H- and 13C-NMR spectroscopy including two-dimensional correlation spectroscopy (COSY), total correlation spectroscopy (TOCSY), nuclear Overhauser effect spectroscopy (NOESY), and H-detected 1H,13C-heteronuclear multiple-quantum coherence (HMQC) experiments demonstrated the following structure of the branched tetrasaccharide repeating unit:
