It is not clear why Francisella produces such a large amount of lipid A without O-antigen, given that O-antigen is critical for virulence Sandstrom et al. Total lipids were extracted from wild-type WT and naxD homologue mutant mut strains of B. Bars represent the average and error bars represent the standard deviation of three biological replicates from one experiment. Unlike the lipid A component of complete Francisella LPS, Francisella free lipid A includes a phosphate modified with galactosamine at the 1 position highlighted in green. P2X7 receptor differentially couples to distinct release pathways for IL-1beta in mouse macrophage. Structural analysis of Francisella tularensis lipopolysaccharide. To our knowledge, Francisella is the only Gram-negative pathogen shown to exhibit this sort of unique outer membrane composition. Support Center Support Center. NaxD is necessary for deacetylation of undecaprenyl phosphate- N -acetylgalactosamine.

The Francisella pathogenicity island. Undecaprenyl phosphate-GalNAc deacetylase assay These assays measured the deacetylase activity of proteins from the F.
