Figure 1. Lipopolysaccharide and its outer membrane translocon LptD/E.

Figure 1

a lipopolysaccharide of S. typhimurium strain LT2. n = 4–40. LPS contains lipid A, core oligosaccharide and O-antigen. b LptD/E complex structure of S. typhimurium strain LT2. The N-terminal domain of Salmonella LptD is generated by modeling, based on the structure of Shigella flexneri LptD. The positions of residues are detected the cross-linking with LPS are shown in magentas, otherwise in yellow. The residues are selected at the N-terminal domain, the hydrophobic intramembrane hole, the lumenal gate and the lumen of barrel.
