Induction of the Citrobacter freundii group I beta-lactamase in Escherichia coli is not dependent on entry of beta-lactam into the cytoplasm.

M J Everett1, I Chopra, P M Bennett.   

Abstract

Induction of the cloned ampC Citrobacter freundii beta-lactamase in Escherichia coli by 6-aminopenicillanic acid was prevented by periplasmic TEM beta-lactamase in the same cell. In contrast, cytoplasmic TEM beta-lactamase did not prevent induction. This result implies that entry of the beta-lactam into the cytoplasm is not necessary for induction of ampC.
