ChEBI ASCII Name Proteus genomospecies 3J-r O-specific polysaccharide
Definition A polysaccharide derivative consisting of a repeating unit of β-D-glucuronosyl, β-D-galacturonosyl and N-acetyl-β-D-glucosaminyl residues linked sequentially (1→3) and (1→3), to the glucuronosyl and N-acetylglucosaminyl residues of which are linked respectively (1→2) and (1→6) an N-acetyl-β-D-glucosaminyl residue and an α-D-glucosyl residue, while the galacturonosyl residue forms an amide with 3-O-acetyl-L-threonine, the complete pentasaccharide repeating units all being linked (1→4). The O-polysaccharide of Proteus genomospecies 3J-r.
