Dissecting Escherichia coli Outer Membrane Biogenesis Using Differential Proteomics

LPS structure and transport in Escherichia coli.
A) Chemical structure of LPS. O-antigen is indicated in parenthesis as it is not synthesized in E. coli K12 derivatives. B) LPS transport from IM to OM. The MsbA protein catalyzes LPS flipping across the IM that is then exported to the cell surface by the Lpt machinery.
