in Neisseria meningitidis, phosphatidylethanolamine typically has acyl chains of C12 and C14 with the first position being occupied with a saturated chain and the second being unsaturated. The recombinant soluble periplasmic domain of the enzyme is active in an aqueous assay but unable to add phoshoethanolamine to lipid A in Escherichia coli strains, lipid A profiles, overview |
