MexBmediated
MexBmediated refers to a process or phenomenon that is facilitated or carried out by the bacterial protein MexB. MexB is a component of the MexAB-OprM multidrug efflux pump found in many Gram-negative bacteria, particularly Pseudomonas aeruginosa. This efflux pump plays a crucial role in the expulsion of a wide range of antimicrobial agents and other toxic compounds from the bacterial cell.
The MexAB-OprM system is a tripartite pump consisting of three protein components: MexA, an inner membrane fusion
