Structure of the O-specific polysaccharide for Acinetobacter baumannii serogroup O1

A polymeric fraction containing d-galactose, N-acetyl- d-galactosamine, and N-acetyl- d-glucosamine was isolated from the lipopolysaccharide produced by the reference strain for Acinetobacter baumannii serogroup O1. By means of NMR spectroscopy, methylation analysis, and chemical degradation, the re...

Description
Summary:A polymeric fraction containing d-galactose, N-acetyl- d-galactosamine, and N-acetyl- d-glucosamine was isolated from the lipopolysaccharide produced by the reference strain for Acinetobacter baumannii serogroup O1. By means of NMR spectroscopy, methylation analysis, and chemical degradation, the repeating unit of the polymer was identified as a branched trisaccharide of the following structure.
