Piperacillin binds to penicillin binding proteins (PBP) located on the inner membrane of the bacterial cell wall, thereby interfering with the cross-linking of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. As a result, cell wall synthesis is interrupted leading to a weakened cell wall and eventually cell lysis."}]
