Correction to Structural Characterization of a Model Gram-Negative Bacterial Surface Using Lipopolysaccharides from Rough Strains of Escherichia coli

Published: July 24, 2014 Figure 1. Schematic of the organization of Escherichia coli LPS. LPS was from the rough mutant J5 strain of E. coli O111:B4, which produces an Rc chemotype with a core oligosaccharide as described by MüllerLoennies et al. The original R mutants, which defined the different chemotypes were from Salmonella minnesota, so in this paper we use the terms Ra/Rc to denote the chemotype of E. coli LPS used according to this convention. Kdo, 2-keto-3-deoxyoctonic acid; Hep, L-glycero-Dmanno heptose; Glc, glucose; Gal, galactose; GlcN, glucosamine. The Lipid A tails consists of four (R)-3-hydroxy-mystic acids, one myristic acid, and one lauric acid. Additional phosphates and ethanolamines on Kdo and Hep have been omitted for clarity.
