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,(1)H COSY, TOCSY, NOESY, and 1H,(13)C HSQC experiments. The polysaccharide was found to contain N (epsilon)-[(S)-1-carboxyethyl]-N(alpha)-(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… CONTINUE READING
