Effect of bacterial dissociation on lipopolysaccharide structure: A study of O-polysaccharide from the marine bacterium Pseudoalteromonas agarivorans KMM 232 (O-form)
Year: 2024
Type: article
Abstract: The lipopolysaccharide (LPS) was obtained from a bacterium Pseudoalteromonas agarivorans KMM 232 (O-form) isolated from a seawater sample collected at a depth of 500 m. The O-polysaccharide (OPS) was isolated by mild acid degradation of the LPS and studied by chemical methods along with 1D and 2D 1 H and 13 C NMR spectroscopy , including 1 H, 1 H COSY, 1 H, 1 H TOCSY , 1 H, 1 H ROESY and 1 H, 13 C HSQC, and 1 H, 13 C HMBC experiments. The following new structure of the OPS from P. agarivorans KMM 232 (O-form) containing 2-acetamido-2-deoxy- d -glucose (D-GlcNAc), d -glucose (D-Glc), d -glucuronic acid (D-GlcA), 4,6- O -[( R )-1-carboxyethylidene]- d -galactose [D-Gal p 4,6 ( R -Pyr)] and two residues of d -galactose (D-Gal) was established:
