Figure 6. A proposed mechanism of MexG/HI-OpmD efflux pump.

Figure 6

The presence of MexG negatively affects the activity of MexHI-OpmD efflux pump. MexG physically interacts with the pump and its substrates such as pyocyanin. In the ligand-bound state MexG could be in a different conformation or could dissociate from the pump, which in turn could lead to increased efflux of compounds.
