Penicillin-binding protein 2 is required for induction of the Citrobacter freundii class I chromosomal beta-lactamase in Escherichia coli.

B Oliva1, P M Bennett, I Chopra.   

Abstract

Involvement of Escherichia coli penicillin-binding proteins (PBPs) in induction of the cloned ampC Citrobacter freundii beta-lactamase by 6-aminopenicillanic acid was investigated. The enzyme was not inducible at 42 degrees C in a mutant thermosensitive for expression of PBP 2. The results imply that PBP 2 is involved in the process leading to induction of ampC.
