Abstract
The O-specific polysaccharide of Providencia rustigianii O14 was obtained by mild acid degradation of the LPS and studied by chemical methods and NMR spectroscopy, including 2D 1H,1H COSY, TOCSY, NOESY, and 1H,13C HSQC experiments. The polysaccharide was found to contain Nε-[(S)-1-carboxyethyl]-Nα-(d-galacturonoyl)-l-lysine (‘alaninolysine’, 2S,8S-AlaLys). The amino acid component was isolated by acid hydrolysis and identified by 13C NMR spectroscopy and specific optical rotation, using synthetic diastereomers for comparison. The following structure of the trisaccharide repeating unit of the polysaccharide was established:
