The Outer Membrane of the Marine Gram-Negative Bacterium Alteromonas addita is Composed of a Very Short-Chain Lipopolysaccharide with a High Negative Charge Density
European Journal of Organic Chemistry (7) (2007)
1113-1122
The complete structure of the lipopolysaccharide isolated from the Gram-negative marine bacterium Alteromonas addita, type strain KMM 3600T = R10SW13T, has been elucidated by means of a combined chemical approach and state-of-the-art NMR and MS analyses. Isolation and characterisation of the lipid A moiety and the core oligosaccharide were pursued separately after either acid or alkaline treatment of the lipopolysaccharide. The structure detected was identified as a novel, highly negatively charged, deep-rough lipopolysaccharide in which a trisaccharide subunit is connected to a typical lipid A glucosamine backbone. Within the core oligosaccharide, a phosphodiester bridge connects a glucose unit to a heptose residue.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
