A glycopolymer was isolated from the marine gram-negative bacterium Sulfitobacter brevis strain KMM 6006 and found to be teichoic acid containing ribitol, glycerine, and N-acetyl-D-glucosamine. The polymeric chain consisted of alternating 1,5-poly(4-N-acetyl-β-D-glucosaminylribitophosphate) and 1,3-poly(glycerophosphate) based on 13C and 31P NMR spectroscopy of the native polymer and the glycoside obtained by its dephosphorylation.
