Structure elucidation of the capsular polysaccharide of Acinetobacter baumannii AB5075 having the KL25 capsule biosynthesis locus.

Abstract

Capsular polysaccharide was isolated by the phenol-water extraction of Acinetobacter baumannii AB5075 and studied by 1D and 2D (1)H and (13)C NMR spectroscopy. The following structure of the linear trisaccharide repeating unit was established: → 3)-β-D-ManpNAcA-(1 → 4)-β-D-ManpNAcA-(1 → 3)-α-D-QuipNAc4NR-(1 → where R indicates (S)-3-hydroxybutanoyl or… (More)
