[Retracted] In Vivo Development of Polymyxin B Resistance in Klebsiella pneumoniae owing to a 42 bp Deletion in the Sequence of phoQ

Figure 3

Interaction between MgrB and PhoQ/PhoP system. MgrB inserts in the inner membrane, with its N-terminus in the cytoplasm and C-terminus in the periplasm, and represses PhoQ, resulting in decreased PhoP phosphorylation.
