LC-precursor ion scan chromatogram of m/z 845.6, showing the identification of undecaprenol phosphate-linked sugars that are involved in the modification of lipid A in F. novicida. A. The major lipid A species (structure 1) in F. novicida is glycosylated at the 1-position with a galactosamine (GalN) residue; a minor lipid A species (structure 2) is modified with an additional glucose unit at the 6′-position. B. C55-P-GalN, C55-P-GalNAc, and C55-P-Glu are the major undecaprenyl phosphate linked sugars detected in the total Bligh-Dyer lipid extract of F. novicida.
