Abstract

The capsular polysaccharide from Acinetobacter baumannii LUH5550 was studied by 1D and 2D (1)H and (13)C NMR spectroscopy. The following structure of the branched trisaccharide repeating unit was established: [structure: see text] where Pse5Ac7RHb indicates 5-acetamido-3,5,7,9-tetradeoxy-7-[(R)-3-hydroxybutanoylamino]-L-glycero-L-manno-non-2-ulosonic acid. The genes in the capsule biosynthesis locus designated KL42 are consistent with the structure established.
