Structure of an acidic O-specific polysaccharide of Proteus mirabilis O5

The following structure of the O-specific polysaccharide of Proteus mirabilis O5 was established by 1H and 13C NMR spectroscopy at 500 MHz, including two-dimensional COSY, TOCSY, NOESY, and H-detected 1H, 13C heteronuclear multiple-quantum coherence (HMQC) experiments: Article Outline 0.
