Role of AmpR in the High Expression of the Plasmid-Encoded AmpC β-Lactamase CFE-1
ABSTRACT CFE-1 is a unique plasmid-encoded AmpC β-lactamase with the regulator gene ampR. It imparts high resistance to most cephalosporins with constitutive high-level β-lactamase activity. Here, the β-lactamase activities and expression levels of ampC with or without ampR were investigated. Result...
