A polysaccharide derivative that is the exopolysaccharide of Acetobacter baumannii strain 54149, the repeat unit consisting of N-acetyl-D-galactosamine beta-1,3 linked with D-galactose as the backbone with the galactose carrying a beta-1,6 linked glucose branch. Most repeating units (~90%) are decorated with beta-2,6-linked pseudaminic acid on the branch (CHEBI:141605).
